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.

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.

Now I couldn't start pfSense anymore it was held on;```

So you tried disabling DHCPv6?

At that screen you should still be able to answer 'N' to the VLANs question and continue the pfSense setup. The duplicate IP warning is just informational. It shouldn't stop you continuing.

I was stuck there. Actually I was not allowed to keyin any imput. All were done automatically eversince starting pfSense.

This version of pfSense was imported on pfSense-2.0.3-RELEASE-amd64.ova download on Internet. Would this .ova have problem?

I also have pfSense-LiveCD-2.1-RELEASE-amd64.iso.gz download. I can create another VM installing this version.

Ok, excellent. Remember those settings! :)

So now there are two further problems to be tackled one at a time.
1. Change the WAN connection to PPPoE directly from pfSense.
2. Add a host adapter so the host also uses pfSense as it's internet gateway.

Personally I would try to do 1 first but it's up to you. Don't try to do both at the same time though it will only introduce further confusion.

Ok I'll do step-1 first without changing Adapter 1 and 2 of pfSense. I'll do direct editing on gui pfSense to change DHCP to PPPoE

How about the devices connection? Still behind the router?

OR
ISP -> Modem -> PC ?

Shall I add the MAC Address of eth0 ?

If unsuccessful I'll add Step-2 which, I suppose, is an addition to Step-1?

I'm not very clear of;

2. Add a host adapter so the host also uses pfSense as it's internet gateway.

Whether add another Adapter to pfSense
Adapter 3
Host-Only Adapter
Name: vboxnet0

And edit /etc/network/interfaces of Host as;```

The loopback network interface

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
Address 192.168.1.2
Netmask 255.255.255.0
Gateway 192.168.1.1

auto vboxnet0
iface vboxnet0 inet dhcp


Please advise.  Thanks

Ok so to do part one, yes, change the pfSense WAN interrface to PPPoE and connect the modem directly the bridged host NIC.
Enter the correct PPP username/password in pfSense. Reboot the modem.
If it doesn't connect check the system and PPP logs in pfSense to see how far it got for clues.

For part 2 that's exactly what I would do though when I read through the documentation I wasn't able to fully understand how the 'host only' adapter functions.
In pfSense go to Interfaces: (assign) and click the '+' icon and bottom to add a new interface. It will be OPT1 but you can rename it, say, HOST, if you like. Enable the interface and give it an IP address and subnet, something you're not using anywhere else. Go to Firewall: Rules: OPT1: and add a rule to allow out traffic, use the default allow rule from LAN as a template. Go to Services: DHCP Server: and add a DHCP sever to OPT1. Since you will only ever have one machine in that subnet you could use static IPs instead.

You have used a /32 subnet mask on OPT1, so there are no other addresses available other than the pfSense OPT1 address. I think (without having read too much of this thread) that yourOPT! is supposed to be a different subnet to LAN, and will connect the host OS through to pfSense.
You need to put a different subnet than on the internal VM-based LAN - e.g. make it the pfSense OPT1 192.168.2.1/24 - then you can make a big (or small) dhcp range, like 192.168.2.10 to 192.168.2.99

Unless you need to have IPv6 enabled here, and your ISP is supplying it via DHCPv6, I would set WAN IPv6 to 'none'.

Nope the PPP logs can be found via the webgui. Status: System Logs: PPP tab.
However I wouldn't worry about that because you have managed to connect successfully, the logs will just detail the connection succeeding.

Hi Steve,

I don't know what has happened here. I'm now posting from another PC (PC2)

After lunch I turned on PC1 but couldn't get VM connected Internet again. I have spent 2 hrs and couldn't figure out the problem.

I have 2 pfSense installed on PC1, but not running at the same time. Both of them worked before Lunch. I have not changed any config nor cabling.

pfSense2.1
pfSense2.11 (adding OPT1)

Now after starting
pfSense2.1
WAN -> em0 -> pppoe
LAN -> em1 -> 192.168.1.1/24

pfSense2.11
WAN -> em0 -> v4: xxx.xxx.xxx.xxxx/30 (static IP)
LAN -> em1 -> v4: 192.168.1.1/24
OPT1 -> em0 -> v4: xxx.xxx.xxx.xxxx/30 (static IP)

VM can login gui pfSense but unable to connect Internet.

It is very strange to me.

satimis

stephenw10

Did you reboot the modem? It will usually only allow connection from one MAC address. Depending on how that is configured it may see it as the physical NIC MAC or some MAC auto generated by VBox. You usually have to reboot the modem to get it to talk to a new device. Possibly the auto generated MAC changed when you rebooted PC1.

Steve

satimis

I couldn't figure out what has happened here. The only way for me to reboot the modem is to switch off and on its power supply. I have done that multiple times.

I also suspect the problem coming from the vNIC? So I did following test on PC1:

Config Host /etc/network/interfaces to connect pppoe
Cable connection: ISP -> Modem -> PC1
Reboot PC
"pon dsl-provider", PC1 connects ISP. Host can browse Internet without problem
Set VM
Adapter 1
NAT
Start VM. It connects Internet without browsing problem.

Reconfig Host /etc/network/interfaces not to establish connection at boot. Switch off/on modem and rebooted PC.

Created another pfSense, naming it pfSense2.12 and config pppoe. It re-starts without problem showing connecting ISP on terminal:
WAN (wan) -> pppoe0 -> v4 xxx.xxx.xxx.xxx (Static IP Address)
LAN (lan) -> em1 -> v4: 192.168.1.1/24

Start VM
Adapter 1
Internal Network
intnet

It can't browse Internet

On pfSense Dashboard
It shows Static IP but not inside the box. ISP nameservers are displayed.
(Please see image attached)

If connection can't be established the Static IP will not be displayed on Dashboard
(please see image attached)

Hmm, have you always been using a static IP with the PPPoe connection? That's unusual.
If the PPPoE connection is not established then I would not expect to see anything in the box. The software cannot query the IP address of a connection that doesn't exist.

Steve

@stephenw10:

In daily operation the connection is behind a router;

ISP -> Modem -> Router -> PC

assign Static IP automatically.

Direct connection;
ISP -> Modem -> PC

on Static IP is for testing only to check whether the vNIC is working properly.

What I can't understand is on pfSense terminal it shows connecting ISP. But VM can't connect Internet.

IT IS VERY FUNNY TO ME !!!

I found out the cause of problem. It is the static LAN IP Address assigned to VM by me.

There are 2 Ubuntu12.04 VMs, say VM1 and VM2, for this test. After starting pfSense, it assigned 192.168.1.102 and 192.168.1.103 to VM1 and VM2 respectively.

Then I edited
VM1 (/etc/network/interfaces)```

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
address 192.168.1.102
netmask 255.255.255.0

VM2 (/etc/network/interfaces)```

auto lo

  iface eth0 inet static
  address 192.168.1.103
  netmask 255.255.255.0
  gateway 192.168.1.1

Rebooted both VMs making sure they work. "sudo ifconfig" showed the correct LAN IP address.

After lunch I started pfSense and was not aware a new range of LAN IP created.

After deleling```

auto eth0
iface eth0 inet static
address 192.168.1.102/192.168.1.103
netmask 255.255.255.0

on their /etc/network/interfaces, rebooted both VMs.  Now they can browse Internet.
