Re: Routing and netconf
Basically, from what I can tell:
1) You must use router 10.230.3.15 to get to hosts 196.28.61.130 & 196.28.61.214
2) All other traffic goes through 192.168.58.254.
I'm not sure why you would expect to get to the Internet via 10.230.3.15 when you only have specific host routes that use that gateway.
Any traffic that is **NOT** to 196.28.61.130 & 196.28.61.214 and needs to go through a gateway will use the default gateway (192.168.58.254).
If the 11.0 server is routing traffic to the Internet via the 10.230.3.15, and your routing is actually identical, then I believe that is the server that is actually misbehaving and not the 11.11 server.

Re: Routing and netconf
Works like a charm on the 11.00 box connected to the same LAN/WAN.

Re: Routing and netconf
When doing a tracertoue, try this:
# traceroute -i lan0 192.28.61.130
This will tell traceroute to use the lan0 interface rather than the one it perceives to be on the same subnet as your default gateway.
