Routing and netconf

NonGuru — Tue, 17 Mar 2009 18:23:49 GMT

I have a an HP box running 11.00 and one running 11.11. Both have identical netconf files. One can see hosts on internet (lan0 10.230.3.1 throught gateway 10.230.3.15) and the 11.11 can't, seems to route everything on the default gateway(192.168.58.254 on Lan1(192.168.58.10).

Any ideas?

Config from 11.11
$ traceroute prtc
traceroute: Warning: Multiple interfaces found; using 192.168.58.10 @ lan1
traceroute to prtc (196.28.61.130), 30 hops max, 40 byte packets

Unless I misunderstand your routing statements, the behavior you see on the 11.11 server appears to be normal.

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.

I guess I used the term Internet badly. The two hosts (static routes) are internet mail servers. The 10.230.3.15 router/gateway is the Internet DSL modem/router. I can't ping the two hosts (or send mail for that matter), as it routes them (I beleive) throught the default gateway which is a WAN with n Internet access.
Works like a charm on the 11.00 box connected to the same LAN/WAN.

Can you ping the 196.28.61.130 & 214 hosts?

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.
