I need to quickly create a solution for forwarding multicast traffic
between two systems, so I though perhaps I could use pf to do just that
by writing some rules along the lines of:
1. pass in on iface A proto UDP ... tag mcast
2. pass out on iface B tagged mcast
And another pair of rules for the reverse direction B -> A.
(Obviously I'd add more options to filter specific addresses, etc.)
Possibly stupid question, but did you set the sysctl(s) to enable forwarding?
$ sysctl net.inet.ip.forwarding
and
$ sysctl net.inet6.ip6.forwarding
will provide the answer (as in, if those values are not 1, forwarding
between interfaces is not enabled)
And there is also mforwarding
net.inet.ip.forwarding
net.inet.ip.mforwarding
net.inet6.ip6.forwarding
net.inet6.ip6.mforwarding
