I'm sorry I didn't see this thread earlier. I have used FreeBSD as a gateway for many LANS and currently I'm running PPTP here using the mpd from ports. I didn't see the beginning of the thread, but in order to make the PPTP clients gateway properly, I had to install an arp entry, because mpd was not responding to arp requests and the clients didn't know to reply through the PPTP port. This stuff is all in the archives for this mailing list within the last year or so. In answer to your question, you need to set the default defaultrouter in the /etc/rc.conf file to the IP of your router. -Jim To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
