Maybe there's a misunderstanding: As I read it Daniel asks for setting the client's *out-going* IP address, something like telnet -b <local-address>. Probably he's on a multi-homed host or has a more complicated IP configuration and has to use a specific out-going address for getting his packets accepted by the server. Ciao, Michael.
