My topology is from an external VPN client from the outside interface on my asa5520, to internal router on the inside interface, then to another router which connects to a WAN client. I have appropriate routes configured on all three devices. The only source IP THAT cannot get through to the WAN IP destination are DHCP VPN clients coming the outside interface. Using the ASDM GUI I have been unsuccessful in finding the appropriate configuration item to add or alter. Any ideas?
