IPv6

Hi there,

(I already posted this under Gen. Discussion - probably not the best place)

I'm running m0n0wall 1.3b15 with an ipv6 tunnel via sixxs.

Things work fine on the WAN and LAN interfaces.  The problem starts when I try to add an additional /64 subnet on my OPT1 interface.

I have the 1st /64 on my LAN interface working fine.

I see these messages in the logs:

Oct 22 17:20:57    rtadvd[13901]: <ra_output> sendmsg on fxp2: Permission denied

Any help would be appreciated.

Thanks!

I have run into the same thing.  I can enable IPv6 on interfaces other than WAN and LAN, but I get a flood of errors if I check 'Send IPv6 router advertisements' on those other interfaces.

it's bridge problem with ipv6,ping ipv6 in monowall response to subnet LAN hosts, not response to subnet OPT1 hosts 
My temporary solution is no bridge function, assigment 1st/64 a LAN y 2st/64 a OPT1 of net/48.

After all these months I still cannot grok that reply.  Looking at the changelog for 1.3b16 I thought that ipv6 on multiple interfaces was working.  I upgraded and turned on router advertisements and again got the flood of errors from rtadvd.

Does anyone know how to get ipv6 router advertisements going on multiple interfaces without a flood of errors?

linuxcat: what is your interface assignment ? RA's being L2 could be broken across vlans and bridges (i have seen this with vlans and vmware for example)

linuxcat: I suspect you have captive portal enabled on this interface ? 

I tried this today and with the portal on, got this message, and with it off, no more messages.  Captive portal sets an ipfw rule to block layer 2 traffic.  This probably should be fixed, but captive portal has no ipv6 support at the moment either.

Wow, you pegged it before I could reply to the first message.
No bridging, no vlans, but captive portal is turned on.

Thank you for finding the cause.
