We have 2 portmasters (PM2), several servers, a cisco to the world, and a
firewall to the internal network.

The cisco is default gateway

The servers and portmasters are on one class C, the dialins are on another
class C.

Because some users have fixed ip, but can dial in on either of the
portmasters, I run routed on all servers, and the portmasters seem to
announce on which portmaster the customer is, so the route gets changed to
the right portmaster.

The traceroute should then go from server to pm1 or pm2 to customer.

However, often the route changes so it goes
server->cisco->pm->client or
server->firewall->pm->client or even
server->cisco->(router at our uplink)->cisco->(router at our uplink) etc.

If I constantly pings the client, I gets pauses where the pings are lost.

What do I do wrong? Shouldn't I use routed on the servers, but only route
default gateway to the cisco, and let it handle the pm1/pm2 route changes?
Or should I have one server running routed? or gated? or what?

Help!!!
