Latest snapsot wireless bridged as well as static not working

AhnHEL

I was having that same MTU issue as xbipin, mtu to the bridge interface was not set at 1500 when i ran the ifconfig command.

Using the below commands fixed it for me on my Alix 2c2

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

xbipin

@matrix200:

I also have bridging issues with the original 1.2.3RC1 build.
In my case if I only set bridging in the wireless interface it doesn't work (I don't use dhcp though and assign static ip's).
However if I set the bridging from the lan interface too it starts working!
This is annoying but I suppose I can live with that.

do u mean to say LAN bridged to WAN works but wireless bridged to LAN doesnt?

No,

What I am saying , it matters in which interface I set the bridging.
If I set the bridging in wireless interface (ath0 to lan) it doesn't work.
If I go to lan's interface and set there to bridget to ath0 then it works.
The thing is , this setting is not retained after reboot and I have to repeat this procedure everytime I want to reboot.
I also get the error message about wrong mtu when bridging but strangely enough the bridge works fine afterwards.

i tried the following release
1.2.3-RC1
built on Sat May 23 03:47:37 EDT 2009

and still sad coz wireless bridged to LAN and wireless clients dont get ip address from DHCP running on LAN interface

DeCex

All works fine here;

OPT1 bridge to LAN

2 PC with with wireless connection
1 Wii gameconsole (wireless client)

If you goto the Status\Interface and look at the OPT1 option. What does it say? "associated" ?. I think i had this issue onces long ago and rememberd it was somethin to do with the OPT1 channel setting. Since im on WAG311T wifi card (Netgear) i hae channel 6 set (Turbo) and have no probelm at all.

xbipin

i guess its not a wireless issue but its a bridge issue and dhcp isnt able to give out ip to wireless clients

Here´my firewall rules

1 for LAN
1 for OPT1

xbipin

its the same rules i got, mayb if u read in older posts ull see that all the debug has been done and config is all perfect and firewall is also not blocking any dhcp packets but its just that dhcp isnt replying properly or something like that

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.

jimp

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.

xbipin

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

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! :)

xbipin

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)
