routing b/w two interfaces of same maching w/o using loopback

hello all,

i am opening up two tap interfaces, both connected to bridge, assigning them IP addresses and want to open up tcp connection b/w them without using loopback interface, so i bind client socket to first tap using SO_BINDTODEVICE option and socket server listening on other tap device.
The problem is that when i m calling connect, it is giving timeout error.

Is it possible two route traffic b/w two interfaces of same machine w/o using loopback interface and kernel hacking

thanx
jaguar

I wonder if intra-network messages could be routed without loopback interface.

Basically, this decision is taken care by kernel. Packets destined to external network are sent to the approproate interface by raising interrupts to the cards. Intra-network packets need not require the intervention of interfaces .... no h/w interrupts and are routed through loopback interface.
