Cisco ASA access ports

While activating AnyConnect and trying to access the ASDM there might be problem to access one of the services.

ASDM and AnyConnect are using both https (SSL/TLS) on port 443 so you need to move one of them to use some other port:

ASA-LAB# show run http http server enable 7443 http server idle-timeout 60 http server session-timeout 40 http 0.0.0.0 0.0.0.0 OUTSIDE http 192.168.100.0 255.255.255.0 INSIDE100

Here I configured the ASDM to use port 7443, so when I will try to connect to the ASA with 

ASDM I will have to insert the port number as show here:

 We can also change the AnyConnect port by configuring it under webvpn:

webvpn  port 8080  enable OUTSIDE  enable INSIDE100  anyconnect image disk0:/anyconnect-win-3.1.04072-k9.pkg 1  anyconnect enable  tunnel-group-list enable

Here I configured the AnyConnect to use port 8080, also note that you will have to add the port in the AnyConnect client:

Any change in the webvpn will force you to shut down the service by issue the command:

webvpn  no enable OUTSIDE  no enable INSIDE100
