I have a problem with having 2 nics and the need for multiple gateways
for IP's that are bound to them, heres my prognosis in detail :-#

Background Scenario :- 

I have a server that is running FREEBSD 4.7-STABLE. 

This server has 2 network cards. 

Each network card has its own pool of IP's and are on different subnets
which are transported by different carriers. 

Details :- 

The servers main hostname is admin.mghost.net the IP is 66.250.145.138,
the default gateway for this is 66.250.145.137, these ips are on the
cogent network, all traffic in/out of the server for the ip
66.250.145.138 should be routed through the gateway 66.250.145.137.
These are all on the first network card which is an realtek card. 

The servers second hostname is test.mghost.net the IP is 69.1.78.8, the
default gateway for this is 69.1.78.1, these IP's are on the internap
network, all traffic in/out of the server for the ip 69.1.78.8 should be
routed through the gateway 69.1.78.1. There are all on the second
network card which is an intel thing. 


The problem :- 

It appears there is no easy way to add a second default gateway,
something I did, which I thought was working, is not. all inbound
traffic destined for the IP 69.1.78.8 is going through the correct
channels and through teh correct nic, however, outgoing traffic is being
routed to the default gateway, through the first NIC, so when people
connect to the IP 69.1.78.8, the traffic is being sent through the first
NIC and through the gateway 66.250.145.137. 

The needed solution :- 

I need something that will allow me to make traffic that is destined for
the IP 69.1.78.8 to be routed through the correct NIC and the correct
router, not the default gateway, so traffic from 69.1.78.8 back out
again, should go via the gateway 69.1.78.1.
