I have two networks on a server. One being my internal network, and the other being an external IP address. This is on Debian Lenny. Here is my /etc/network/interfaces file:
auto eth0 iface eth0 inet dhcp auto eth1 iface eth1 inet static address 24.249.108.xxx netmask 255.255.255.224 broadcast 18.104.22.168 gateway 22.214.171.124
I can reboot my system and sometimes eth1 is accessible from SSH, and other times eth0 is accessible. Then sometimes eth1 will just stop being pingable alltogether. This is a fairly fresh install of Debian, and the only thing I have running is VMWare Server 2.0, bridged to both of my network connections.
Here is what my route looks like:
Destination Gateway Genmask Flags Metric Ref Use Iface 126.96.36.199 * 255.255.255.224 U 0 0 0 eth1 172.16.130.0 * 255.255.255.0 U 0 0 0 eth0 default wsip-24-249-108 0.0.0.0 UG 0 0 0 eth1 default plumbco-router. 0.0.0.0 UG 0 0 0 eth0
