eth0 is the default gateway for the box
eth1 has a gateway for the local LAN, 192.168.1.1
The LAN has several VLANs, 192.168.105.0 for instance.
192.168.1.1 is the default gateway for the entire LAN. This is a switch with routing enabled, and it's also 192.168.105.1, etc.
From the problem box, traceroute 192.168.105.x shows that that traffic heads out eth0 despite all my efforts, i.e. static routes; i have modified sysconfig/network-scripts/route-eth1 as here:
192.168.105.0 via 192.168.1.1
192.168.105.0 via 1.247
it is critical that I be able to interact with this box to/from my other VLANS. I'm stumped.
