I am starting over with a drawing.
The user out in the cloud is a client who wants to connect to https://www.help.megacorp.net:9443
Then I want the ASA do PAT on 9443 to 443 and forward that traffic to the host in the LAN (10.100.37.21)
help.megacorp resolves to 22.214.171.124
The logs on the router and ASA5520 show nothing. I must have something basically wrong.
If you need more detail from the config let me know.
Thanks a million,
