Hi, I operate a small WISP, everything works well except for UDP peer to peer traffic, I recently installed verlihub on the network, connecting to the hub happens over TCP so users have no problem logging in, however, no one can connect to each other. The users can ping each other no problem, TCP no problem but for some reason UDP p2p between users doesn’t want to work. Same with peer to peer SIP connections. If I manually setup port forwarding from the PPPoE concentrator to the pppoe user(s) DC++ works (doing / maintaining that will be a nightmare), peer to peer VoIP doesn’t work unless I setup either a EoIP tunnel or a VLAN. I’ve wondered if it doesn’t have something to do with ARP (tried ARP-Proxy) but with no luck, so basically, everything works in a test environment whilst on the same broadcast domain. Below is a diagram of the network, things to note; there aren’t currently any firewall filter rules, PPPoE users are only masqueraded if their dst is 10.0.0.0/24 and all HTTP traffic gets routed to 10.0.0.253.
Any Ideas?
