My guessing was instead if FreeBSD is capable of driving an ISDN card or a V.35 card (or possibly a X.21 card), with the goal of routing IP traffic *through* FreeBSD. In fact, I don't want to export all my LAN to the Internet, but just the FreeBSD machine, leaving the other +50 Unix and PC computers hidden. So, to my knowledge, the router *must* be the FreeBSD PC (the other, obvious solution, is to give 2 LAN interfaces to FreeBSD and put a router with a LAN address different from the internal standard, but this will be more expensive). Another solution could be to write by myself the driver for the WAN card, using the already available PPP: for this task I need maybe some hints from you, to start working. That's all; thank you for your support. -------------- Niccolo` Avico E-mail: nico@trs.inet.it T.R.S. S.p.A. Via V. G. Galati, 91 Tel: ++39-(0)6-4063911 00155 ROMA Italy Fax: ++39-(0)6-4060300
