samba - Oct 2001 - Linux w/ samba and pc on different subnet address, how?

I am new to samba... sorry if this question is a FAQ but I have been
unable to find any clue in the doc I have read.

I have installed samba (2.0.10-2) on a RH7.1 box with ip=192.168.xxx.xxx
and I would like to serve file to pc's on ip=192.167.xxx.xxx (that are
NOT across a router)
What should I do in smb.conf (I believe) to see them?

Regards.
