Latest snapsot wireless bridged as well as static not working

matrix200 · Current network "hardware" : Running 2.2RC in Virtualbox 4.2.16.

I think it is not a firewall issue at all because in my setup I don't have dhcp and just have my laptop with an ip in my lan subnet and unless I do the bridging from lan to wifi interface , I simply can't access it (ping , telnet etc).
Sounds like bridging/routing issue to me.

I would probably also help to see the output of "ifconfig -a" and also a copy of the rules for the wireless interface for both those who say it works, and those who say it doesn't.

Perhaps there is some telling difference between the two.

doesnt work for me now doesnt even with static ips on wireless bridged to lan

MTU on ath0 is 2290

Is this proper?

Ran the following commands in console to set all interfaces to 1500 mtu including bridge0 and thats how it started to work again for me.

ifconfig vr0 mtu 1500
ifconfig ath0 mtu 1500
ifconfig bridge0 destroy
ifconfig bridge create

Change the vr0 above with your interface name for LAN

updated to the recent snapshot and the same thing again. dhcp wont work on the wireless. alix, atheros 5212, full install.
ifconfig shows mtu of 2290 on ath0 and on bridge0
also, after upgrade I'm getting error message invalid parameter while loading firewall rules 2 and 3.
Here are those rules from config file (nothing was changed, this is how they are in config file):
<rule><type>pass</type>
<interface>optXXXX</interface>
<max-src-nodes><max-src-states><statetimeout><statetype>keep state</statetype>
<os><source>
<any><destination><any></any></destination></any></os></statetimeout></max-src-states></max-src-nodes></rule>
<rule><type>pass</type>
<interface>opt2</interface>
<max-src-nodes><max-src-states><statetimeout><statetype>keep state</statetype>
<os><source>
<any><destination><any></any></destination></any></os></statetimeout></max-src-states></max-src-nodes></rule>
what these rules do? opt2 is my wireless.

AhnHEL

Did you run the ifconfig commands i listed above to see if that resolves your wireless problem?

I'd reboot my Alix box and try again myself to see if the commands consistently resolve the issue but my Alix box is remote to my location and I cant afford the downtime if the commands dont help.

covex

screenshot in your post, is it before you've recreated the bridge or after?
your card is in promiscuous mode here

ath0: flags=8943 <up,broadcast,running,promisc,simplex,multicast>metric 0 mtu 1500</up,broadcast,running,promisc,simplex,multicast>

mine does not have it after I change mtu on it.

AhnHEL

Screenshot is taken after.

Wont both vr0 and ath0 be in promiscuous mode because they are bridged?

covex

I don't know what is going on! ???
My wireless works right now but vr1 (LAN) mtu is 1500, ath0 mtu is 2290 and bridge0 is 1500.
The only thing I changed was switching from channel 6 to channel 10 in the wireless settings. I'm afraid to reboot my router now! :)

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

Hope it will be helpful for others , here is my ifconfig -a output
Like I said it works after the bridging from lan to wireless interface is performed.

@xbipin:

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)

channel.png_thumb

xbipin

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

cmb

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.
http://snapshots.pfsense.org/FreeBSD_RELENG_7_2/pfSense_RELENG_1_2/

AhnHEL

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.
