I have an unusual problem. I've been attempting to fix this issue or confirm the issue is not with the firewall and I have kind of run into a road block. This is my problem as I understand it. A client of mine has a VPN tunnel built over a point to point connection of some kind (this client is fairly new to me) and is unable to access some hosts on the remote end of the VPN tunnel from the LAN side of the firewall. The LAN IPs are NAT'd as they leave the network from the HPH-Point-to-Point interface to the remote end. Just as a point of reference, the LAN IP of 220.127.116.11 is said to be working, however the range of 18.104.22.168 - .50 is not. I've tried packet-tracer but with the NAT happening over a VPN tunnel I am not sure if I am doing it correctly.
Any ideas on how to troubleshoot this would be greatly greatly appreciated. I've attached a running-config of the firewall.
