I have a service on LAN multicasting UPnP, port 1900. Other devices on
LAN discover the service without problems. My AppVM does not detect it.
Packets from the server looks like "protocol: UDP, port: 1900, source
ip: $SERVER_LAN-IP, destination ip: 22.214.171.124"
How do I make the UPnP multicast reach an AppVM, i.e. how do I forward
the traffic on port 1900 to the relevant VM?
I have played around with
but without success. I am not completely new to IPTABLES, but somehow I
lost a point somewhere. When should I use 126.96.36.199 as destination
in iptables commands and should I use the IP of sys-firewall/app-vm.
(this is quite a replica of
that didn't receive a follow-up answer)
