I want to set up a simple unencrypted tunnel between a linux-server (running SLES9) and a client (running XP SP3). The reason for this is that there are many network devices in between and the client does build up many many IP connections. I want to test, if the process of building up these connections is the core of massive latency problems with this application. (There is a WAN between server and client).
Now the question: There are a lot of howtos on how to set up GRE tunnels (which seems appropriate here) on linux and cisco.
But how do I set up a GRE-tunnel on the XP-client?
