WireLess WAN - Infrastructure (BBS) mode? Wireless Client - 2.0 RC3
-
When I checked the status of the wlan card with ifconfig ath0_wlan0 several times I noticed it was actually scanning the network since it showed a different channel each time I executed the command.
After I changed the radio settings on my FritzBox to Adjust Radio Channel Settings and set the WLAN standard to 802.11n+g+b. The were able to find each other and the connection is now up and running! Great!
However now I still can't get any traffic over the pfSense box. Question is how to define the rules and do I need to add a static route on the FritzBox as well.
FritzBox: WAN - NAT - Wifi (192.168.0.1) + DHCP + DNS
pfSense: WAN (192.168.178.2/24) + WANGW (192.168.178.1) - LAN (192.168.0.1/24) + DHCPQuestion is what NAT setting is needed in this case and do I need any specific rules to be defined?

Good progress.
@Bo:
FritzBox: WAN - NAT - Wifi (192.168.0.1) + DHCP + DNS
pfSense: WAN (192.168.178.2/24) + WANGW (192.168.178.1) - LAN (192.168.0.1/24) + DHCPI don't understand this information. For a start, having two subnets with the same address parameters hanging off two different machines is bad practice. At the very least its going to complicate your troubleshooting which you have already found complicated. Change the LAN subnet on pfSense to something unique on your network (it conflicts with the WiFi on FritzBox.)
I thought you had WiFi between pfSense and Fritz so why aren't the addresses in the WiFi subnet?
@Bo:

Now that you have your wireless link working I suggest you adopt the simplest configuration, get that working and then we can look at some optimisations.
Change your pfSense WAN link IP address to DHCP. Then the default LAN firewall rules and NAT settings should allow access to internet. Check the pfSense WAN link has a correct IP address. From the pfSense console check you can ping an internet site (e.g. www.google.com) then check from one of your pfSense LAN clients.

Sorry guys but the IP address of the internal FritsBox network was a slip of the pen! These are the correct settings:
FritzBox: WAN - NAT - Wifi (192.168.178.1) + DHCP + DNS
pfSense: WAN (192.168.178.2/24) + WANGW (192.168.178.1) - LAN (192.168.0.1/24) + DHCPHowever I tried the set the WAN port of the pfSense box to DHCP. The FritzBox! thinks that the IP address is set to 192.168.178.25 but the pfSense box does not get an IP address it is still 0.0.0.0 in this case.
If I enter an fixed IP address I am not able to route any data from or behind the pfSense box to the FritzBox or further upstream.
Could it be that I am just bumping into a bug and should I try to change back to pfSense 1.2.3?

You could be bumping into a software bug but I think its more likely to be a configuration "bug".
Why did DHCP not work on the WAN interface? It could be helpful to have the dhclient output from the system log. Please post the output of the pfSense shell command clog /var/log/system.log | grep dhclient
Why can't you route data from pfSense? Please post the output of the pfSense shell command netstat -r -n ; ping -c 4 192.168.178.1
You can issue pfSense shell commands in a SSH session to the pfSense box or from the pfSense web GUI: Diagnostics -> Command Prompt and type the command in the Command box then click the Execute button.

My FritzBox indicates that there is a connection and it provided an IP address to my pfsense box:

@Bo:
Does this help?
YES in that it gives an explanation why you couldn't get data through your pfSense box: Despite issuing at least 15 DHCP requests the box didn't receive a recognisable answer to that request hence the WAN link (ath0_wlan0) doesn't have an IP address. (dhclient is the DHCP client program)
Here's an example from one of my pfSense boxes (so you have an idea of a "good" DHCP request):
Aug 6 08:48:42 pfsense2 dhclient[14231]: DHCPREQUEST on vr0 to 255.255.255.255 port 67

Are any other computers (e.g. laptops) laced near your pfSense box able to associate with the Fritzbox and display an external web page (e.g. http://www.pfsense.org)?
Does your pfSense see any response to its DHCP requests? Issue the pfSense shell command```
tcpdump -i ath0_wlan0 -v -e -c 20 -

Yes, I am sitting next to my pfSense box and typing this stuff from my macbook which is connected over Wifi as a DHCP client to the FritzBox. So a connection is possible.
Here is the tcpdump with the WAN interface as a DHCP client

@Bo:
Yes, I am sitting next to my pfSense box and typing this stuff from my macbook which is connected over Wifi as a DHCP client to the FritzBox. So a connection is possible.
Thanks. Useful datapoint.
I've adjusted the spacing in the following trace and deleted some entries that don't seem relevant.

The Fritzbox doesn't appear to send a DHCP reply (maybe it did send a DHCP reply that got damaged and was discarded) but about 0.005 seconds later appears to send an ARP (Address Resolution Protocol) request asking the system with IP address 192.168.178.34 to reply to 192.168.178.1 (so 192.168.178.1 knows the MAC address of 192.168.178.34). Is bc:05:43:bc:85:91 the MAC address of the FritzBox WiFi interface?
The FritzBox appears to be ignoring the DHCP request (perhaps because it doesn't see it). Does the FritzBox have some sort of packet tracing facility or DHCP logging that could be used to see if the DHCP request is arriving there?
As before I'll adjust the spacing and remove some entries that seem irrelevant.

Does the FritzBox have some sort of filter or firewall that could be causing it to ignore transmissions from your pfSense? Again, is there some sort of tracing facility or logging in the FritzBox that might provide some more clues about what is going on?

Looking at the WLAN logfile of the FritzBox! it turns out that there is some kind of an authentication problem:
06.08.11 20:57:21 WLAN registration failed (2,4 GHz): Authorization failed. Name: sargas, MAC address: 00:80:48:52:FF:3D.When I turn off the ecryption the pfSense box properly gets an IP address and the connection works!
Finally some progress, but of course one would need to turn on WPA2 again.On my FritzBox I have choosen the option "WPA + WPA2" other options are "TKIP (WPA)" and "WPA2 (CCMP)"
I am not completely sure how to configure my pfSense box.When I choose the options:
WPA: Enable WPA
PSK: "MySecretKey"
WPA Mode: Both
WPA Key Management Mode: Pre Shared Key
Authentication: Open System Authentication
WPA Pairwise: BothWhen I look into the WLAN logfiel of the FritzBox! it indicates that the pfSense box is properly registred
06.08.11 21:30:57 WLAN device registered (2,4 GHz). Name: sargas, IP address: 192.168.178.20, MAC address: 00:80:48:52:FF:3D, throughput: 11 Mbit/sThe logfile on the pfSense box also shows that the DHCP client is properly registred:
Jan 2 00:02:52 sargas dhclient: Starting add_new_address() Jan 2 00:02:52 sargas dhclient: ifconfig ath0_wlan0 inet 192.168.178.20 netmask 255.255.255.0 broadcast 192.168.178.255 Jan 2 00:02:52 sargas dhclient: New IP Address (ath0_wlan0): 192.168.178.20 Jan 2 00:02:52 sargas dhclient: New Subnet Mask (ath0_wlan0): 255.255.255.0 Jan 2 00:02:52 sargas dhclient: New Broadcast Address (ath0_wlan0): 192.168.178.255 Jan 2 00:02:52 sargas dhclient: New Routers (ath0_wlan0): 192.168.178.1But if I look at the dashboard I don't see the right IP address but:

It is strange that dhclient reports being assigned an IPv4 IP address but ifconfig doesn't report an IPv4 address.
I don't know what the DS in
media: IEEE 802.11 Wireless Ethernet DS/11Mbps mode 11b
means.
Can you get your link to operate in 802.11g mode rather than 802.11b? You may need to make adjustments at both ends OR it may be forced into 11b mode by an 11b only device.
-
Switching over to 11g mode does not seem to be an issue. Signal strength is at its maximum, Both sides report that they communicate with each other in 11g mode:
sargas 192.168.178.20 00:80:48:52:FF:3D 54 Mbit/s WPABut still only if I turn off the ecryption the DHCP client receives an IP address.
-
I wonder if it would help to tighten the encryption parameters step by step and record the results. On pfSense change WPA mode from Both to WPA2 and make the corresponding change in Fritzbox. DHCP exchange? If no, tighten WPA2 Pairwise from Both to AES and make corresponding change in Fritzbox. Does DHCP work? If not try WPA2 Pairwise as TKIP and make corresponding change in Fritzbox. etc.
I saw a software upgrade on my netbook break WiFi. WiFi on windows laptops continued operating. I changed my pfSense access point: WPA2 Pairwise from Both to AES fixed the problem.
I'm not very confident my suggestion will help you discover a working set of parameters but might provide some useful data.

Just out of curiosity, please show your interface assign page.
I saw you using ath0_wlan1 which is a virtual second IF on your atheros card. That one directly would be ath0.Chances are you configure the 'other' interface which is not currently assigned to a network.
I've taken a screenshot from my test box which contains two separate atheros cards (ath0 and ath1) and a virtual one (ath0_wlan1) just to show you:
Why do you have a second virtual IF at all? Just assign ath0 to your WAN.
Depending on the pfSense build you're using, there seem to be some inconsistencies with real and virtual IFs.
I had an ALIX system where I couldn't bridge vr1 and ath0; using vr1 and ath0_wlan1 worked immediately.
Just a guess, though… -
Meanwhile I've tried to thighten up the Wifi encryption from scratch but so far I haven't found an encryption option that works (didn't try WEP ;-D).
I am quiet sure I've tried all possible combinations, but no succes so far!
I've tested the option to define a virtual Wifi card as well, but pfSense does not allow me to define a virtual Wifi card a Infrastructure BBS.
For the record, here are my interface assignments:
WAN: ath0
LAN: vr0
OPT1: vr1 -
@Bo:
I've tested the option to define a virtual Wifi card as well, but pfSense does not allow me to define a virtual Wifi card a Infrastructure BBS.
The FreeBSD man page for ath says
The driver supports station, adhoc, adhoc-demo, hostap, mesh, wds, and monitor mode operation. Multiple hostap virtual interfaces may be configured for simultaneous use on cards that use a 5212 part. When multiple interfaces are configured each may have a separate mac address that is formed by setting the U/L bits in the mac address assigned to the underlying device. Any number of wds virtual interfaces may be configured together with hostap interfaces. _Multiple station interfaces may be operated together with hostap interfaces to construct a wireless repeater device. _
The man page (or at least this paragraph) leaves unclear whether multiple station interfaces may be operated WITHOUT a hostap interface.
-
Although it would be nice to also be able to configure the pfSense box as an secondary AP next to the infrastructure (BBS) connection, but that would be the icing on the cake.
I am refuse to believe that I am the first one to bump into this issue and strongly have the feeling that there is some easy workaround, but …...............
what's causing the security conflict? based on the ifconfig ath0_wlan0 output I have the feeling that the box is switching to IPv6 mode without having it configured (see log in my reply on Posted on: August 06, 2011, 04:17:23 pm).

@Bo:

My readings of the forums suggest it is much more common to use a pfSense WiFi link as an AP than as an AP client. I think your post is the first mention I have seen of a Fritzbox. This suggests your configuration is probably fairly rare.
@Bo:

I don't know what is causing the security conflict. I don't know what facilities there are in FreeBSD to debug this kind of issue. Concerning the IPv6: for some releases now FreeBSD has "automatically" configured "link local" IPv6 addresses based on MAC address for those interfaces with a MAC address. It is rather unlikely that enabling encryption on a WiFi interface would also turn it into "drop IPv4 traffic" mode if the interface is in client mode but not if it is in AP mode. (I have an ath interface in AP mode using encryption and successfully passing IPv4 traffic.)
-
Well I've used the same pfSense box for multiple years as an Wifi AP using WPA+WPA2 as encryption and never experienced any problems. It might be the other side of the line: the Fritz!Box causing all the issues.
I'll go and look for another AP and check if the pfSense box can establish a secured connection in Infrastructure mode with this AP.
-
Yesterday i tried to connect an ALIX with ath0 cards to a Linksys WRT54GL wireless AP (which is running DD-WRT).
I was able to get an IP from the DHCP pool (hence encryption [WPA2 AES] is working) but wasn't able to pass traffic. I couldn't even ping anything on ALIX WAN.And you were right, Bo, Infrastructure mode only works on the virtual ath0_wlan1 interface, not the native card IF ath0.
I think there were issues with some of the snapshot builds in the past where you couldn't assign IFs correctly. Will try a recent snapshot tonight and report back. -
Good to hear I am not alone out there!
