Well I have a program that sets up the rest of my rules already. I
think I need to add a special case for this one website that I need to
force out the eth2 interface. So I think I need to add that to the
very end.

I need to be able to hit 142.46.226.26 on eth2. The website associated
to this is https://one-pages.on.ca.

I have the route statement on the server.

default         gw.ch1.cable.ex 0.0.0.0         UG    0      0        0 eth1

Ultimately I need to add an LDAP entry to the end users address book,
but I can start with them browsing the address book online  start.

Basically I want to force any traffic destined to 142.46.226.26 out
eth2 all the time. There will never be a situation I need to hit that
site from the public internet.

Thanks.
