Re: Dual-NIC GnuGK ignoring host-based routing table

[Armando Lima <armando.f.lima@xxxxxxxxx>]

I had a similar issue on Asterisk box. I think, It is not a matter of GK application but a matter of routing issue of your linux box, I mean, networking issue. Could you provide the printout of "netstat -nr" command on your linux console? On that printout you will see, what's the real default IP/interface. May be there is no need to put public default IP address on your eth1 interface (private interface). I think that's causing the problem.
Thanks

Because of our firewall configuration and other issues, I have the following:

eth0.  Directly connected to outside network.  Default route to the internet.
eth1.  Connected to inside network.  Has route to 10/8 and a /25
that's in the public IP range.

What's happening is that GnuGK is sending call setup messages to the
H.323 gateway that has a public IP over the eth0 to the internet,
rather than relying on the routing table in the host.  From the
command line, a traceroute correctly shows that because there's a
specific /25 in the kernel routing table it sends the packets over the
internal network, not the external, and my internal routing is
configured correctly.

Is there some reason that GnuGK is using the wrong interface?
