This is again about igmpproxy.
As I mentioned earlier to be RFC compliant (RFC 2236 IGMP V2 and 3376
IGMP V3) we must send IGMP packets with Router Alert in IP header (RFC
2113).
It is very easy to code but a problem with pf arises. To be able to send
these packets we have to add "allow-opts" in pass out quick on 'Upstream
Interface'.
I tried to modify \"let out anything from firewall host itself\" rule in
/etc/inc/filter.inc and it worked.
Please answer these questions:
1) I can't see a way to insert "allow-opts" only for upstream interface
at the igmpproxy package configuration web-interface. Is there a way?
2) Is it wise to add this functionality via another option in
System->Advanced options (or where)?
3) Do we need at all this functionality (Router Alert in IP header)?
Thanks,
Eugene
