Hello, I have two freeswitch servers connected over vpn like the following: FS A <> openvpn<> FS B Server A has the ip address 172.16.1.2 Server B has the ip address 192.16.1.2 openvpn gateway is on 10.8.0.1 Both the servers have the common acl defined to not nat the above addresses like following: <list name="nat.auto" default="deny"> <node type="deny" cidr="10.8.0.0/24"/> <node type="deny" cidr="172.16.1.0/24"/> <node type="deny" cidr="192.168.1.0/24"/> </list> <list name="localnet.auto" default="deny"> <node type="allow" cidr="172.16.1.0/24"/> <node type="allow" cidr="10.8.0.0/24"/> <node type="allow" cidr="192.168.1.0/24"/> </list> I am able to call the extensions on server B from server A. However if i try calling the extension on server A from server B i get an error of [CS_NEW] [WRONG_CALL_STATE]. The only way i can make a successful call from B to A is when i add the network of B in the acl on server A as follows: <list name="domains" default="deny"> <node type="allow" domain="$${domain}"/> <node type="allow" cidr="192.168.1.0/24"/> Is there a reason why i need to do this? Thanks Rajil
