Problem Description
when update CAS verison to 7.0
Following configuration didn't work:
nat server global X.X.X.X : 8081 inside server X.X.X.X:8080 (CAS server)
when from public network access the cas server, it will open the web page of the firewall , not the CAS web
Process Analysis
check the NAT session, sessions are all normal, with no issue.
CAS server reply to NAT session normally.
Afrer confirming with the CAS R&D team , that CAS 7.0 was using 80 port not 8080 port for the WEB from the client side, and then use mapping function on the server to map 80 to 8080.
So we change the nat inside server port to 80, then client can access the CAS WEB.
Solution
Old:
nat server global X.X.X.X : 8081 inside server X.X.X.X:8080
New:
nat server global X.X.X.X : 8081 inside server X.X.X.X:80
