I'm not networkguru either, but a few tips:
- your routers have to route multicast packets (this is usually not the
case for security reasons), plus they have to route them to the correct
subnets.
- if you have more than one network interface in your client machine, make
sure you route the multicast packets to the appropriate router (or
subnet). I've run into this problem in the past. :)
- last but not least I really don't know how secure is routing your OpenSG
connections over LANs (if you do that), I don't think the protocol was
designed with security above everything, as it's meant to be used in
separated cluster systems. And AFAIK the client has to find the servers
via multicast (at least that's what I _think_) even if you use streamsock
for the actual data transmission, and I'm not sure how secure that is over
untrusted networks.
Hope this helps,
Akos
