RE: Selecting an ethernet line

Yes you can bind to a specific IP address.  What I would do is create a
virtual IP address on your AS400.  Just like adding a physical with a couple
of parameters changed.  Then on your default router add the two physical IP
addresses as routes to the Virtual IP address, which must be in it's own
subnet.

For example with both Ethernets in the same subnet:
Eth01 = 10.0.0.1 / 255.255.255.0
Eth02 = 10.0.0.2 / 255.255.255.0
VirtIP= 10.254.254.1 / 255.255.255.255

Route 1 = 10.254.254.1 255.255.255.255 10.0.0.1 metric 1
Route 2 = 10.254.254.1 255.255.255.255 10.0.0.2 metric 2
