All. I am having some trouble getting Solaris to act as a router. I
have 3 servers with a direct connection between each of them,
respectively. I need s2 to act as a router between the private
networks on s1 and s3. I can ping s1<=>s2 and s2<=>s3, but not
s1<=>s3. I have /dev/ip ip_forwarding set to 1 on s2. I'll try to draw
a diagram and give all of the pertinent info. Does anyone know why I
can't get this to work?

Thanks in advance.

Hey,

you need IP-NAT, cause your s2 must translate the packages
form the net 192.168.100.X to the other net 192.168.200.x

NAT is not needed here. Just make sure you get your routes right: on
s1 192.168.200.0 should be routed through 192.168.100.101, not
100.100. The same thing for s3 - 192.168.100.0 should be routed
through 192.168.200.100.
I hope I didn't overlook anything.

JACKPOT. Thanks all.

solaris 10 has the command routeadm, with enables or disables routing,
so i assume you have some older release. Whats about udp and other
protocols, does ndd /dev/ip respect only ip (i think so)?
