Hey.. I'm having a little trouble getting multiple tunnels to connect simultaneously.
Here's my setup: I have a main office and 3 satellite locations. My Zyxel USG50 is at the main office and at each satellite I have a Zywall 2 plus.
Here's how I want it to work: At the main office, I have a phone system that is connected to my network, at each satellite location, I have an ip phone looking for that sytem. I'd like to have all three locations connected simultaneously with all 3 iphones connected to the phone system at the main office.
I can successfully build a tunnel between the main office and each of the locations, but not simultaneously. When 2 of the locations VPN connections are enabled at the same time, it constantly connects, and disconnects alternating connections... Site 1 will connect for a few seconds while Site 2 is disconnected and then Site 2 will connect and Site 1 will disconnect.
