[OpenIndiana-discuss] weird network issue, choosing a default interface

[Carl Brewer]

Hey,
I have a weird problem I don't quite know how to fix.
I have an OI server, with two ethernet interfaces, 203.6.241.37 on 
e1000g0 and 192.168.2.4 on rge0.  The 203.6.241 network is a real one, 
the 192.168, as you know, goes nowhere except local LAN stuff.

Weird thing :

traceroute: Warning: Multiple interfaces found; using 203.6.241.37 @ e1000g0

The rge4 interface, 192.168.2.4, is being used, for some outgoing 
traffic.  Of course, it's not finding its way home.
um?

  netstat -rn shows

I think the default also being on rge0 is the problem, but I don't know 
how it got there, or how to remove it.

Any clues?

Thank you
