Subject: Ipaddress modification

Hi, 

I am trying to run two socket client-server programs on the same machine
which use the same port nos ( also same ip address) independent of each
other.

I am planning to capture the bind request sent for a particular port no
and change it to a differen ip address and send it to the kernel and any
data sent to the port should be correctly transferred to the pertaining
program by maintaining a table.

Only way I could think of is to change during the bind request since I
need to modify it before the actual binding happens. Anybody got any
idea on this?

Thanks in advance.

Bala.
