New to the forums! I have a problem with an IP Site Connect setup that is driving me nuts. I have 2 sites. One site has the Master, and 1 Peer. The Peer is actually at another location, but is connected to the main site via a 5.i Ghz Microwave link. Essentially it is plugged into the same switch as the Master. Both Master and Peer are hooked into an HP 1920 switch. The switch is connected to the outside world via a 4G cellular modem. The other site is a Peer, and is sitting inside of a broadband connection. It has a static, public facing IP, as does the cell modem at main site. I have been over and over all of the IP related configurations, and cant find a flaw there. Right now the Master is sitting in a DMZ to eliminate any port forwarding issues until this is figured out. The issue is that the Peer at the end of the 5.8 link can talk to the Master just fine. The offsite Peer can talk to the Master as well. I can not get any Peer to Peer traffic. From the Master i can not see any information about the Peers that it is talking to. The Firmware on the Master and the Peer that are on the same LAN have an older firmware, but are the same. The offsite Peer has a newer problem. Am i dealing with a firmware issue? Possible a Bad Master? All repeaters are MTR3000. Anyone dealt with this symptom?
