Latest snapsot wireless bridged as well as static not working

DeCex

after changing the mtu of ath0 to 1500, still wireless clients dont get ip from dhcp nor with static ip clients works

Sorry if this questionn sound stupid,

you have not tick the "Deny unknown clients" in the DHCP setting?
you´v tried changing the default channel on the OPT1 card ad see if the MTU changes? (try choosing another from Auto,Save and check MTU after saving and see what it say)

i have already played around with all those settings a lot but doesnt make a difference bcoz its not the wireless that the issue but its just the dhcp or routing due to which the wireless client doesnt get an ip and with the same config the march release works perfectly fine

covex

well, onhel's commands are helping but in my case I also have to disable/enable wireless interface in gui so it would start dealing ip addresses to the clients.

xbipin

the commands for me when i run them then the LAN and wireless as well as the bridge interface all have 1500 as mtu but it still doesnt give out ips so i disable and then enable wireless from the gui but still it doesnt doesnt give ips and when i check the mtu go back to the wierd values, they r not getting saved.

in the system logs i saw certain packets were dropped,
UDP from 0.0.0.0:68 to 255.255.255.255:67

dont know if thats affecting it or no

xbipin

i thing i dont understand is earlier if the wireless client was assigned fixed ips then atleast wireless bridged to lan used to work but that doesnt now and i was checking the filter log and saw this entry
pass in on ath0: 192.168.0.18 > 224.0.0.251: igmp v2 report 224.0.0.251

192.168.0.18 being the ip manually configured in the wireless client and shouldnt it be going to 192.168.0.1 which is the firewall ip instead of 224.0.0.251, plz correct me if im wrong as i am a newbie to dhcp etc

This all seems to be related to ath changing MTU on its own, which appears to be a "feature" of the patched ath(4) we're using in 7.1 based snapshots. It should be impossible to end up with a 2290 MTU on a bridged ath interface, we set it to 1500 twice and never set it to anything other than 1500.

Try a 7.2 based snapshot which doesn't have the ath patch.

Thanks for the heads up Chris.

Is this patched ath(4) driver going to be continued in 1.2.3 stable because that "feature" is too important for ath(4) to be reverted back to being unpatched?

The patched version seems to have made using a wireless interface on pfSense very problematic.

cmb

I don't know what to think about that ath patch at this point….it's better for some people, worse for others. Also we're not yet sure which FreeBSD version 1.2.3 final release will end up using, it may be switched to 7.2 for unrelated reasons.

There will be no patched ath on 7.2 builds. I upgraded my primary production AP yesterday and it's worked fine since, but it usually took a couple weeks to start displaying problems with the previous version so it's hard to say at this point. It hasn't magically changed MTU on me though.

AhnHEL

I'll be trying the 7.2 build next I'm at my ALIX site within the week and report back my results then. Thanks again.

covex

i think i've tried 7.2 version already with the same results. or may be it was update from 7.1 to 7.2… don't remember now, but i'm going to do clean install of 7.2 right now and test it.

... I can't find the option in 7.3 to install full install embedded kernel. without that it wont run on my Alix. embedded 7.3 from CF does the same thing to mtu switching it to 2290.

xbipin

i have tried it with 7.2 and its the same, doesnt work in spite of me playing with almost all settings in the gui as well as using those commands, the mtu shows as it used to in 7.1

@xbipin:

what do your /tmp/ath0_setup.sh and /tmp/bridge0_config files contain? What is the result if you run those commands manually?

xbipin

this is what i get when i enable wireless from the GUI initially and in which wireless clients cant get ip using dhcp as well as manually configuring cant surf

and when i try to laod file /tmp/ath0_setup and /tmp/bridge0_setup it says file not found

xbipin

when i run the ifconfig bridge0 destroy then the cpu usage jumps to 100% and remains like that only till the time i disable wireless from the GUI

wallabybob

and when i try to laod file /tmp/ath0_setup and /tmp/bridge0_setup it says file not found

On my system (1.2.3-RC1 built on Mon Apr 13 16:35:28 EDT 2009 ) there is no /tmp/ath0_setup but there is a /tmp/ath0_setup.sh and there is no /tmp/bridge0_setup but there is a /tmp/bridge0_config.

/tmp/ath0_setup.sh gives

Once the bridge is successfully created and wireless is working, are both the LAN interface and wireless interface supposed to be in promiscuous mode?

Thats what my ifconfig shows on a working system.

Also, in the GUI, when I go to Status/Interfaces, LAN and ATH are both listed as learning in Bridge0

covex

anybody knows what happened to the "install embedded kernel" option in the LiveCD installer? I caqn't find it in 7.3

cmb

@onhel:

Yes.

AhnHEL

So it looks like from xbipin's output results that even though the mtu is being set correctly with both interfaces and the bridge, the problem is that lan and ath are just not going into promiscuous mode.

What if they manually enable promiscuous mode:

ifconfig vr0 promisc
ifconfig ath0 promisc
