Hi @ all, ok the Title is a bit confusing. But i will explain my problem. I got an ISA Server behind a Linux router. This router is connected to the Internet. The ISA-Server and the router are connected over a network cable.I want to make a temporary Lan Connection to the Server, the ISA Server should close this connection just like a RAS-Connection which has a timeout after (e.g. 3 min "no-traffic"). Ok this is a really strange question ;-) thx@all greetz stephan
