You're probabaly using RIP (version1), and it doesn't support CIDR => Lots of trouble. What I would do was something like this. Let all your servers and the firewall have a static default route to the cisco router, and not run routed or gated on these. Enable OSPF on both the cisco and the portmasters, OSPF has sigificant advantages over RIP, it supports CIDR among other things. RIP version2 could also solve your problem. If you need help with this Tele Danmark has consultants that can help you, but it'll cost you ... /Jesper -- Jesper Skriver (JS249-RIPE), Network manager Tele Danmark DataNet, IP section (AS3292) One Unix to rule them all, One Resolver to find them, One IP to bring them all and in the zone to bind them.
