There is lan and xl2tp clients both connected to the same server.
I need that multicast would be relayed to both sides: from lan to l2tp clients and vice versa.
In particular WSD traffic: IP 239.255.255.250, ports 3702 and 5355
xl2tpd doesn't support RFC 4045, which provides L2TP extensions to support efficient carrying of multicast traffic. That was the only reason I suggested a WS-Discovery proxy, I don't have any suggestion as to which one.
