Hi, all, I got a weird program. The two endpoints can register on the GK, but when one dial the other, can't get through. The GK, and both endpoints are behind different firewall. The endpoints are behind routers. The GK is behind a physical firewall, but it's NATted to the Internet. The setting of the GK is listed as following: [Gatekeeper::Main] Fourtytwo=42 Name=GKTest TimeToLive=60 StatusPort=7000 TotalBandwidth=150000 [RoutedMode] GKRouted=1 H245Routed=0 CallSignalPort=1720 RemoveH245AddressOnTunneling=1 AcceptNeighborsCalls=1 AcceptUnregisteredCalls=1 SupportNATedEndpoints=1 DropCallsByReleaseComplete=1 [Proxy] Enable=1 ProxyForNAT=1 ProxyForSameNAT=1 When the GK and both endpoints are working in the local network, they are working fine, but don't when network is what I said above. So, can anybody tell me what's the problem is? Any help will be appreciated.
