Thi is my architecture:
LAN1<----> GK1<----> NAT BOX<---------------->GK2<--------->LAN2 [Private IP] | PUBLIC IP
GK1 and GK2 are configured like a proxy. When LAN1 EP calls LAN2 EP is all right, but when LAN2 EP calls LAN1 EP there is a trouble. The LAN1 EP seem to be unreachable. Infact GK2 send message RAS message to private IP address of GK1, while the GK1 is registered with GK2 like a nated endpoint. Can someone help me? I can resolve this by iptables, but i prefer dont't use it.
Best regards Paolo
This is my configuration file:
