I have not implemented this my self but I have read that Haproxy, a load ba=
lancer, can do this as well. Haproxy will send the reply using the interfac=
e where the requests came from.

I get what you're saying about policy-based routing, but isn't that applica=
ble only to connections initiated by the server?=C2=A0 Can policy-based rou=
ting also do "All connections initiated externally and coming through the r=
outer ip address so-and-so goes through that router"?

that is correct because traffic came from router A and B use the main
routing table... your solution is to use policy based routing....
create additional two routing table aside from the default or main
routing table.. for incoming traffic for A or B.... mark or tag it ...
upon out going.. your policy rule state that packet tag for A goes to
gateway of=C2=A0 A and tag for B goes to gateway of B.. non tag packets
goes to the main routing table's default gateway...
fooler.
