Hello all, I've posted this message on several news groups without any results, maybe here someone can help me... I still have problem with GRE through Linux router and Win2k clients but additional information have occured. Let's start from the beginning: My subnet is as follows: 192.168.49.0 ----- linux router ------ 172.19.1.0 ------> Win2k clients When first client is trying to connect to VPN server out side our office all packets are sent through "linux router". When he finishes the connection and second client wants to make a new connection no GRE packets are sent through router. If I down and up interfaces on "linux router" everything works OK as earlier - GRE packets are transmitted through router. If I don't down and up interfaces but wait eg. for next day everything also works OK. It seems for me that some "timeout" variable is set on my linux router but I didn't set anything. Can you tell me where I can change this "timeout" on my router? For me it should stay in /proc/xxxx? but what next? Thanks, Marcin
