Hello Ivan,
I'm afraid there is no out-of-the-box solution available by now. But I
would think it's not that complicated to extend the nic_bridge to allow
clients to communicate with each other. By now, the nic_bridge is held
quite simple. It doesn't check the destination of ip-packets from it's
clients, just brings them on-line. It only inspects and modifies dhcp
requests from the clients (and vice versa).
To reduce work for this task I've attached a modified version of the
l4linux run-script, where l4linux and our simple web-server test are
started, and communicate with the network via the nic_bridge. With that
script I can communicate with the l4linux instance anywhere from my LAN
(and vice versa), as well as with the dummy webserver, but both cannot
speak to each other. (The run-script requires a pre-configured bridged
tap0 device to work properly.)
I hope that brings you a little bit further.
Best regards
Stefan
