	You want to look at policy routing and iproute2.

	I basically do that now.  I have a big fat Broadband pipe
with a single IP address and a slower, more reliable, ISDN line
with a large routable address space.  Outgoing connections from
that address space for things like web (http) are flagged and
masquaraded and policy routed out the big fat pipe, while DNS and
smtp (inbound and outbound) go by way of the ISDN line.
