I'm tryng to a attach my Lan to an existing intranet using, as a router, a ppp dialup connection. I would like to give all the hosts on the Lan access to the outer network altogether, and, as a start, I've choosen to run Rip. The ppp router is the standard FreeBSD user implementation, connecting to a SunOS pppd 2.1.2 - but that's just coincidental and I think it doesn't concern my problem. In order to allow the external routes to be passed on through the ppp link and viceversa, I'd have to inform rip running on my Lan about the existence of a distant gateway, located on the other endpoint of my ppp connection, ppp0 interface. Also, in a similar vein, the Rip on the intranet has to know about the routes to my Lan through a distant gateway located on the FreeBSD, tun0 interface. So I have to write the relevant entries in the two /etc/gateways file on the two router machines. MY PROBLEM: ----------- The distant gateways set in the /etc/gateways of both machines, don't seem to work - I mean the proper routes are not installed. That happens even if I set the passive option in the /etc/gateways files. This situation changes only if, while the ppp connection has been winded up and the endpoints are talking each other, I kill and restart the routed processes on both machine. In fact only then the distant gateways are aknowledeged and Rip does its work. Needless to say that, at the first reboot of one or of both machines, the problem arises again. MY SUSPECT: ----------- The distant gateways can't be inserted in the Rip routing table, because they reside onto a dialup interface (tun0 and ppp0 respectively), that does not actually "exist" until the link is up and operational. But if that true, what's the solution? Maybe, especially when using dialup interfaces, installing gated instead of routed ? Thank you, and sorry for my long story. Marco
