It works well for mDNS with my chromecasts
But for WS-Discovery, no matter what source IP I use, "empty", "1.1.1.1" or "1.1.1.2" it just does not manage to let WS-Discovery work from one vlan/subnet to another.
In fact, with "empty", it almost works : probe requests reached the other subnet, that answsers with a probe-match. But Windows has the good idea to see the probe-match packet, but since the source IP is outside it's subnet, it doesn't try to resolve it...
I would like/need this UDP to act like a proxy for WS-discovery, and replace do something similar to NAT, which I thought could be the 1.1.1.1 or 1.1.1.2 source, but in fact sadly no...
Would you be willing to look at the ws-discovery protocol and implement some other mechanism to be able to act as a ws-discovery proxy (lots of documentation show this is allowed by the protocol but I could find no implementation of this anywhere).
Thanks in advance for your reading.
Hello, is there any solution to this issue? I confirm that with UDP Broadcast relay on Port 3702 and Broadcast Address 239.255.255.250 Windows does receive the packets, but for whathever reasons they are disregarded - indeed probably they originate from the wrong subnet...
Thanks!
