Is it okay to change the webvpn port on a ASA5505 to 443?  If yes, can someone help me with the commands?

Thanks -

simple way is through the ASDM
Change the default port 443 to whatever port you want

Do I need to change them in these two places (screenshots).  

I currently have it set to port 500.  I want to change it to port 443.

Thanks

It is the same setting, reachable on several screens on ADSM. If you change the value on either screen it will be changed on the other screen as well, automatically.

lrmoore: The ASA only has one web-server for VPN. You cannot have anyconnect and clientless on different ports.
