All,
We have a subnet with a public IP address fronted by a pfsense
(1.2.3R) box with routing and OpenVPN enabled and configured. We're
testing this with a product that uses multicast - the server is in the
network protected by the pfsense box, and there will be one or more
clients connecting to it from the field.. While most network
functionality is present, the multicast traffic is not being seen on
the client.
Does pfsense/OpenVPN support multicast in this kind of arrangement?
We've added in the IGMPProxy package, which so far doesn't seem to be
doing anything for us, though we may not have configured that
correctly.
Thanks,

I do not think igmpproxy will be in any use here.
Try routing multicast IPs/subnet over the tunnel explicitly.

I'm a complete newb at multicast stuff - never used it before. Since
this traffic will be completely contained over the OpenVPN link,
should I be using (per this link:
http://www.tcpipguide.com/free/t_IPMulticastAddressing.htm) addresses
from the administratively (or locally) scoped range?
Also, what might a route statement look like for multicast - different
than normal unicast routing, or pretty much the same?
Thanks,
Kurt
Don't try to route all multicast addresses (like 224.0.0.0/4) find out what IP address(es) your application is using and
try to route only this one(these ones). Do not forget to allow it in Rules.
Route statement will look exactly like for 'normal' unicast.
Remember: I never tried that, just do not see why it will not work -))) I guess
it is worth to try.
Evgeny.
