ASA remote access problems

jason.hsu — Tue, 12 Mar 2019 06:03:06 GMT

Desperately need ASA assistance. VPN connects and can pass some traffic, i.e. server shares/RDP. Unable to ping any remote LAN address, seeing in the log that return traffic to VPN subnet is denied, the questions is why or what is denying it. Every interface has any/any allowed, it makes no sense why the traffic would be denied. Also, having issues with a VOIP app/softphone; I suspect it is the same deny problem affecting ping that is causing the VOIP issue. Unfortunately the trace output and deny log entries provide absolutely no clue as to what the issue is. I've gone through multiple threads with the same same behavior with no positive results from suggestions noted.
