Hello, I have experienced this on two separate networks. The backbone in both case is a Cisco Cataylst swicth (one was 1900 the other 2900). FreeBSD v3.3 is in use at both networks. 10.0.0.128/255.255.255.192 routed to access server (10.0.0.7) for dialup customers After some time of no activity on the network anyone whois dialed in to the access server can not contact the machines on 10.0.0.14,10.0.0.15 The machine all have the correct netmask being: 10.0.0.1 (router) 255.255.255.224 10.0.0.2 (mail) 255.255.255.224 10.0.0.3 (www) 255.255.255.224 10.0.0.7 (access server) 255.255.255.224 10.0.0.14 (proxy1) 255.255.255.224 10.0.0.15 (proxy2) 255.255.255.224 The mail machine is always accessible, maybe becuase it has radius and named running, keeping the connection to the access server and client alive. Externally to the network I can at all times traceroute to the dialup customer, and the proxy servers. As soon as I trace route to the proxy servers and 'open' the connection, the dialup customer can begin to use the proxy. The proxy will remain 'open' to the dialup user unless no data is transfered for more than 5-15 minutes. When it is not working the client cannot access either proxy. If a connection to one of the proxies is opened, the other proxy becomes available. The access server and router's ethernet interfaces are set the the correct netmask, and ip classless is set on both routers (10.0.0.1 & 10.0.0.6) A bainaid is currently in place which solves the problem. On the individual proxy machines i have set a ping to ping itself eg I have ping 10.0.0.14 on proxy1 and ping 10.0.0.15 on proxy 2. Any help ideas to solve this would be much appreciated. Note 10.0.0.x is not the actual network used.
