So I am just testing connectivity via IPs and Ports that I know for sure are allowed out on a VPN that has a ACL. The VPN exits the Outside interface however I get reverse-path failed when choosing the Inside interface (where source address would be coming from) and "denied by configured rule" on Outside ACL when Outside interface is chosen. Does it make any difference in Packet-Tracer if what you are trying to test is VPN source/destination subnets?
