Installed the pfSense-Full-Update-1.2.1-TESTING-SNAPSHOT-20080727-1206

I ran the ifconfig command and got this;
fxp0: flags=8843 <up,broadcast,running,simplex,multicast>metric 0 mtu 1500
fxp1: flags=8843 <up,broadcast,running,simplex,multicast>metric 0 mtu 1500

lo0: flags=8049 <up,loopback,running,multicast>metric 0 mtu 16384
bridge0: flags=8843 <up,broadcast,running,simplex,multicast>metric 0 mtu 2290

This is from 1.2 -stable ifconfig log. (works)

yeah it won't let me bridge my wireless with my LAN either, i mean it says it does it, but then it just sits on "learning" in the Interfaces tab in the "Bridge (bridge0)" category.

EDIT: Update, about 20-30 mins after bridging the connections unsuccessfully the router rebooted on it's own which worried me, but then upon loading the connections seem have to successfully bridge!

Updated to the latest snapshot, and the problem continues. I have done further testing on this. When booting up the interface is now showing an MTU of 1500. However, after switching to Access Point mode, it automatically changes MTU to 2290. (Disregard the IP, I tested without bridging so I could try to determine which feature/function caused the MTU to change.)

Before enabling AP mode:

ifconfig ath0

ath0: flags=8843 <up,broadcast,running,simplex,multicast>metric 0 mtu 1500

It's definitely Access Point which is causing the MTU to be 2290. If I switch the interface to Ad-Hoc, the MTU is 1500. The moment I switch it back to Access Point, it becomes 2290. My guess is, this is some behavior in the driver itself. Perhaps pfsense could do a 'ifconfig ath0 mtu 1500' after setting the interface parameters.

sullrich

We commited a change to enforce mtu 1500. Please try a recent snapshot.

JTY

I have upgraded to the latest RC1 snapshot, and the problem still continues. Once Access Point is enabled, ath0 changes MTU to 2290.

JTY

I decided to ask on the freebsd-net mailing list, and the response I got was, that 2290 is the default MTU for 802.11.

JTY

Any chance hostapd is resetting the MTU to 2290? I just looked at it's source code, and it appears that it may be setting it (see line 86), http://hostap.epitest.fi/hostapd/devel/hostapd_8h-source.html and (see line 241) http://hostap.epitest.fi/hostapd/devel/driver__bsd_8c-source.html.

weird… the last ifconfig we run on bringing up a wireless card is now 'mtu 1500'. My ath card hasn't shown this behavior in hostap mode, it's always shown 1500 without this recent change so it's not an issue with every ath card.

If anyone finds additional information on this please let us know. I'll be doing more wireless testing as time permits over the next week.

Ok heres the deal with me. (20080730-0226)

With no security It works fine, I get an IP address, With WEP It also works fine.

As soon as I enable WPA It will never connect. Even after I disable WPA and either choose no security or wep it still deos NOT work.

Can anyone else test with WEP or no security on initial install BEFORE enabling WPA to confirm it's the same with other hardware?

I have not had a chance to look at the MTU in this process, but if it does happen only when WPA get's turned on it may point us in the correct direction.

(Utilizing a Cisco ABG card in an Acer5620z Laptop.)

Many thanks,
Tom

mtu 2290 on ath0 and bridge0

Moetop

THANK YOU!

ifconfig ath1 mtu 1500
ifconfig bridge0 destroy
ifconfig bridge create
ifconfig bridge0 addm ath1 addm axe0 up
(where axe0 is my LAN interface and ath1 is my Wireless (opt1) interface)

Works perfectly!

NOTE If you do not have any security or WEP the MTU does not set itself to 2290 so wherever the problem it is, it's only when you enable WPA. Hopefully they can find the piece of code, or create some to set the interface MTU teardown the bridge and recreate!!

@JTY:

Did some testing, not sure if anyone found this before. Anyway…

After bridging the Wireless with the LAN, the following is appears when running dmesg:

bridge0: invalid MTU for re0

I checked the bridge0 interface, and it had an MTU of 2290, just like ath0. Obviosly that MTU is invalid for a standard ethernet NIC, thus it refuses to join bridge.

From there, I attempted to set ath0 (Wireless) MTU via pfSense webConfigurator, but the MTU setting was ignored. So, I manually set it via the shell. However, bridge0 still had an MTU of 2290 after changing ath0's MTU.

Finally, I decided to manually destroy bridge0, and recreate it. Now, that I had ath0 set with an MTU of 1500, both ath0 and re0 would have the same MTU.

ifconfig bridge0 destroy
ifconfig bridge create
ifconfig bridge0 addm ath0 addm re0 up

After recreating the bridge with both devices having an MTU of 1500, the bridge worked properly. The only left was to create a firewall rule to allow traffic in on the Wireless interface, which I did via the webConfigurator.

Hopefully the above is of use to somebody.

Loaded the pfSense-Full-Update-1.2.1-RC1-20080804-0805

After reboot i had no OPT1 interface associated. I reqoqnize that one and went in and set the channel to 6 maually then it got associated (is was set as Auto by default). This the error found in log before i set the channel: kernel: ath0: unable to reset hardware; hal status 12. I have a feeling that WPA Pairwise cant be handle by any client. Is now set to TKIP mode now, which works for me.

The MTU is fixed now i think, all was at 1500 after reboot. Wireless client (WinXP) connected and I can surf from it. Thanks again for all your works for this GREAT firewall/router. Ill keep try updating to newer version whenever thare time for it and report back unsuall stuff from this machine and this newbie user :p

Wireless works …. wiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii :P

Oh anotherthing, when entering the Status\Traffic Graph, when graphic graph is showing, try click on Status\Traffic Graph again. Menu dont show fully.

JTY

Wireless is now working for me.

i hate to break the party but my wireless still wont work. mtu is 1500, security with wpa2/aes and i don't even see the wireless network in the list on my xp client. interface status for wireless says 'no carrier'

Goto "Interface" menu and try set your OPT1 channel manually (1-11), then goto Status+interface and check afterward if you still get no carrirer.

it worked, now i can see the wireless network from my laptop but i still can't conect. well it connects but pfsense wont give dhcp info to the laptop. setting static ip is not helping.
i can get dhcp info through stand alone ap connected to pfsense no peroblem though.

I can confirm the same problem when bridging LAN and WiFi with 1.2.1-RC1 / built on Wed Aug 6.

My notebook is connected, but no DHCP lease. So I tried with static IP assignment, no ping…

covex

same here. alix2c3, wistron cm9, wifi bridged to lan.

I'm running a build from the 10th, and no problems with wireless.
