With respect to routing tables, the answer is a definite no. Routing tables
operate only at the IP-address level (network layer), and protocols are the
next level up (transport layer -- TCP or UDP).
With respect to iptables ... I cannot immediately think of a way to do
this, but iptables offers an awful lot of flexibility, so I would not rule
out some tricky solution, especially in a context where the gateways are
NATing routers. But I have nothing specific to suggest.
