Hi Carlos, when you configure GnuGk as [Endpoint] to another gatekeeper, it will use its own NAT traversal method if the parent is a GnuGk also. But as you noted it can't use H.460.18 in that case. Are you using the ForwardDestIP switch to forward the dialed IP ? Right now we are doing the neighbor selection by the dialed prefix. Maybe we need something to select neighbors by dialed IP, too ?
