      Also holding here for long time```

      ....

      Error : hostname nor servname provided, or not known
      ....

      That's expected behaviour as it tries to obtain an IP address via DHCP (and fails) and then tries to get the time from an NTP server (and fails).

      @satimis:

      WAN (wan)  -> em1  -> NONE (DHCP)
      LAN (lan  -> em0  -> 192.168.1.1

      Ok, so which adapter is which? Is the router still in it's standard mode, handing out IP address on it's LAN? If so then probably have the interfaces the wrong way around. This worked earlier. You set the interface that is assigned to the pfSense WAN to 'bridged interface' and pfSense recived an IP on its WAN from the router. It was em1 there too though so perahps you have changed the WAN adapter to 'internal' in VBox instead of the LAN.

      @satimis:

      VM Ubuntu 12.04 desktop

      Network -> Adapter 1
      Bridged Adapter
      eth1 (not eth0)

      It can ping 192.168.1.1 but unable to ping yahoo.com
      Also on browser I can login pfSense

      The Ubuntu VM that we are using to configure pfSense should have only one adapter enabled on it and it should be type 'Internal'. It is shown as any of the VMs I have on PC1 in my diagram. It should be set to use DHCP in Ubuntu so that you can see when it is correctly receiving an IP from pfSense.

      It seems likely that you have accidentally set the pfSense VM WAN adapter to internal and the LAN adapter to bridged. In that instance the pfSense LAN would be accessible via a bridged adapter on the Ubuntu VM because they are both bridged to the same physical NIC in the host.

      If that is the case you need rectify this by either reassigning the interfaces in pfSense, WAN as em0 and LAN as em1, OR change the adapter types in VBox so the the correct adapters are bridged and internal.

      Forget about MAC addresses for now. You may have to spoof the WAN MAC address in pfSense if your ISP requires that

      @satimis:

      A side question, how to draw your diagram?

      I used giffly.com gliffy.com. The first time I used it hence the colours are at bit odd. Haven't worked out how to change that yet.  ::)

        Hi Steve,

        pfSense was imported on "pfSense-2.0.3-RELEASE-amd64.ova" download on pfSense website.

        Remark:
        I'm confused here.  Physical NIC-1 (eth0) is onboard (motherboard) and physical NIC-2 (eth1) is a PCI-e Gigabit NIC.  On host they are displayed correctly.  However on pfSense and VM NIC-1 becomes eth1 and NIC-2 eth0

        Changed eth0 and eth1 back to their original MAC Addresses.  Started pfSense

        Adapter 1
        Attached to: Bridge
        eth0

        Adapter 2
        Attached to: Bridge
        eth1

        VM 12.04 Desktop

        Adapter 1
        Attached to: Internal Network
        Name: intnet

        $ sudo ifconfig

        
        eth0      Link encap:Ethernet  HWaddr 08:00:27:10:8c:3d  
                  inet6 addr: fe80::a00:27ff:fe10:8c3d/64 Scope:Link
                  UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

        lo        Link encap:Local Loopback  
                  inet addr:127.0.0.1  Mask:255.0.0.0
                  inet6 addr: ::1/128 Scope:Host
                  UP LOOPBACK RUNNING  MTU:65536  Metric:1

                  RX bytes:1312 (1.3 KB)  TX bytes:1312 (1.3 KB)
        
        

        $ ping 192.168.1.1
        connect: Network is unreachable

        I think my problem is pfSense can't establish a second connection to ISP via the virtual NIC.  Because Host is already connected to ISP.  Seemly second connection is NOT allowed unless behind a physical router.

        Other advice noted with thanks.

          The pfSense VM needs to have :

          Adapter 2
          Attached to: Internal Network
          Name: intnet

          That is the adapter that is then set as the pfSense LAN interface.

              You changed the Ubuntu VM adapter type. That has to be Internal also so it can talk to the pfSense LAN.

              Do you have the router connected to the physical NIC that is bridged to the pfSense WAN adapter?

                Do you have the router connected to the physical NIC that is bridged to the pfSense WAN adapter?

                No.  If PC1 is connected behind a router.  It worked already, about 2 days ago.

                Present connection:
                ISP -> Cable Modem -> PC1
                Interface - pppoe

                  Hmm, OK. So if both the pfSense LAN and the Ubuntu NIC are on the same internal network then either the DHCP server is not enabled on the pfSense (it would be enabled by default) or the Ubuntu VM is not set to use DHCP.
                  In your second setup you can see the Ubuntu VM sees the interface as UP but isn't receiving an IP.

                  If you have the router in place then it will hand out an IP to the pfSense WAN and you will be able see immediately if you have the correct adapters assigned to the interfaces.

                    Hi Steve

                    The problem is my modem only has 1 IP address to assign.  Debian Host is getting this IP address before pfSense starts up.  I must sort out this problem first.  Secondly login and password are needed for assigning IP address.  Where shall I enter them to assign the IP address to pfSense in order to get connection to Internet?

                      Well you could do that but as you say you need to be able to enter the PPP username/password to pfSense and you can only do that (without resorting to manually editing files) via the webgui. To access the webgui you need to sort out the connection between the pfSense LAN interface and Ubutu VM you're using for administration.
                      If you put the router back inplace between the modem and PC1 then it will hand out a private IP to pfSense which you will be able to immediately see in the pfSense console. That will make it much easier to determine that you have the LAN interface assigned to the correct VM adapter and that that adapter is configured correctly.

                        Cannot you just add serial port in Virtualbox and use that as console?

                          You could but there's no need to do that you can already access the virtual VGA console. To configure the WAN for PPPoE you pretty much need to do it from the LAN side via the webgui.

                          Any second opinions on this are welcomed. As I said earlier in the thread I've used VBox only a few times and not recently so most of what I've said here is based on research rather than experience.

                            Only have ESXi and Hyper-V boxes available ATM, so… afraid I won't be of much help. I kinda don't understand what's the trouble here then. The web GUI does not work with WAN down, or what? If it does not, what's the problem with assigning some static temp IP to WAN meanwhile, just to get it running?

                              There are two issues.
                              The first is configuring the pfSense WAN interface to connect using PPPoE via a bridged adapter in VBox to the physical NIC and the cable modem. However we havne't yet actually tackled that because of the second issue…
                              Configuring the pfSense WAN to PPPoE needs (or is very much easier) to be done from the LAN side. Here the LAN interface is connected to an internal virtual network only so we have added an Ubuntu VM on that same network in order to fire up a browser and point it at the pfSense webgui. Currently the Ubuntu VM is not receiving an IP from the pfSense DHCP server. This should be pretty easy to accomplish. It's not helped by the fact that earlier access to the pfSense webgui was established via some accidental bridging route.

                              If you're up for it read back through the thread, try not to shout at the computer to much!  ;)

                                Hi all,

                                Performed following steps but still fail.

                                Connection
                                ISP -> Modem -> PC

                                Make following changes:

                                Host

                                /etc/network/interfaces```

                                The loopback network interface

                                auto lo

                                #(configure debian host to connect to the pfSence router via the LAN port)

                                
                                pfSense:

                                According to following document:-
                                pfSense initial configuration with ADSL WAN
                                http://www.interspective.net/2012/05/pfsense-initial-configuration-adsl-wan.html

                                
                                ....
                                The first thing you want to do is use a web browser to connect to your old modem / router and set the WAN interface to 'Bridge Mode'. Once you've logged in you will need to find the WAN type....
                                
                                

                                First I'm not allowed to touch the modem, impossible making change on its settings.  Besides there will be no sense using the router to continue this test.  My goal is using vRouter (pfSense)

                                I think my chance of success being remote?  I'll buy a new router after switching to the new ISP on the coming April (the current router is on loan).

                                  If you are not able to configure the modem in any way, you cannot use pfSense to dial PPPoE. That's pretty much the whole story.

                                    Hi,

                                    Thanks for your advice.

                                    I consider not to spend further effort here because less than a month I'll use a new ISP.  Then I'll try again before purchasing a new router.  I'm subscribing Static IP.  I'll make request to the new ISP for changing the settings on their ONT.  They'll provide ONT not cable modem for HTTH Optical Fibre Network.  My current ISP is not providing Optical Fibre Service.

                                    I have the photo of the ONT attached here which is provided by the new ISP

                                    There are 2 ports.  I think I can use them connecting my 2 PCs?  But how to assign LAN IP to VMs without a router?

                                      You don't need to put your router in bridge mode because you have a separate modem and router. You have removed the router entirely leaving just the modem which expects to see a PPPoE connection.

                                      Here's the think though. You are making this far more difficult than it needs to be by trying to do everything at once. The way to solve problems like this is to do in one step at a time. Right now you're trying to solve the PPPoE connection, the connection to the host and connection to the Ubuntu VM simultaneously. You are also changing many things between each post so that diagnosing what effect the changed have had becomes far more difficult.

                                      The 192.168.56.X address given by the host only adapter to the host is an address given out by VBox when it's NATing. You probably don't want that.

                                      Here's what I would do:
                                      Solve one thing at a time. So first I would setup the connection between the pfSense VM and the Ubuntu administration VM.
                                      Please put the router back in place so that it's handing out IPs. Setup the pfSense VM with two adapters as you did before:

                                      pfSense
                                      Adapter 1
                                      Bridge
                                      eth0

                                      Adapter 2
                                      Internal Network
                                      intnet

                                      Set the pfSense WAN interface to DHCP. It should receive an IP address on the WAN from the router. Now you know you have the correct adapter assigned to the WAN.

                                      Set the Ubuntu VM adapter to:

                                      Adapter 1
                                      Internal Network
                                      intnet

                                      Set Ubuntu to use DHCP. Now it should receive an IP address from the pfSense DHCP server. If it does not we will try to solve that first before doing anything else. We need that connection work.

                                      Steve

                                        Set Ubuntu to use DHCP. Now it should receive an IP address from the pfSense DHCP server. If it does not we will try to solve that first before doing anything else. We need that connection work.

                                        Set connection as advised;

                                        ISP -> Modem -> Router -> PC

                                        also set config as advised.

                                        Started pfSense followed by VM

                                        Login gui pfSense
                                        Wan -> DHCP
                                        -> Applied changes

                                        Status -> Interfaces
                                        Status  down
                                        DHCP  down [renew] (no function on clicking)

                                        Rebooted pfSense, it held here;```

                                          Ok, well we have some new information at least!
                                          That duplicated IPv6 address is probably because both the pfSense WAN and the Host, PC1, are requesting addresses using the same MAC address. They share the same physical MAC. I'm unsure why that didn't happen before. There is probably a work around by spoofing the MAC but if you don't need IPv6 you can just go to Interfaces: WAN: and set the IPv6 configuration type to 'none'. I assume you had set that to DHCP. Obviously leave the IPv4 type as DHCP.

                                          So you had no problem connecting to the LAN from the Ubuntu VM? Did it receive an IP from the pfSense DHCP server? You can check it in Status: DHCP leases:

                                            Before changing pppoe back to DHCP I have put the MAC Address of eth0 "00:26:18:44:b6:1a" there (IIRC).  During changing pppoe to DHCP I deleted that MAC Address.
