In theory, if you can get the GRE routers to forward IP Multicast
properly, this should work. We've had lots of issues with routers that
don't really do IP Multicast properly however, although this seems to be
happening less frequently.
When you say "the FOG is created", do you mean that you have the same
group signature at this point on all servers? I.E. the contents of
/etc/opt/SUNWut/gmSignature match? And you've restarted SRSS on all
servers since the last group signature change?
If you snoop the "private" side addresses, do you see multicast traffic
from the remote servers through the tunnel?
What does utadm -l say? If you really don't want to route the private
network traffic to the public side, you'll need to use utadm -a, not -A
or -L.

Hi All.
I appreciate that this is not supported and may be beyond the bounds of what
can be done.
We have 2 sites (Chelmsford and Cambridge) and 3 V210's (2 in Chelmsford 1 in
Cambridge) running SRSS4.
The Sunray Interfaces is connected to a Vlan on each site before being sent
over the network to the terminals.
The plan is to join the 2 Vlan's together with a GRE Tunnel.
I have dropped the MTU to 1480 to allow for the overheads in the GRE Tunnel.
The FOG is created and working in Chelmsford.
I can see all the Terminals on both sites in the Web admin.
What I cant do is see the Server(s) at the remote site or get the terminals
to connect through the Tunnel.

Am I missing something ?
Any pointers or ideas will be welcome.
Thanks
