Hi, I see this topic in LARTC: Virtual Circuits over TCP/IP sockets I'm interesting about this, I know that in FreeBSD it's posible via netgraph but I didn't see any usable solutions for linux. I know about Frame Diverter but it's not suitable for my purpose. My problem: I have breezenet microwave network with some nodes which are routed and my clients want use my network as a transport net and want to have point-to-point connection. Fig. Topology of network client1 || ~~~~~~~~~~~~~~~~~~~~~~~~~~~~microwave network~~~~~~~~~~~~~~~~~~~~~~~ Access_point --- |switch| --- Node_router1 / / / Node_router2 / / / Node_router3 --- |switch| --- Access_point ~~~~~~~~~~~~~~~~~~~~~~~~~~~microwave network~~~~~~~~~~~~~~~~~~~~~~~ || client1_router How to sent _everything_ (e.g. arp) from client1 to client1_router? I cant use any tunnel. It's posible with linux ? With regards PSIkappa psi _at_ atlantis.sk
