ASA 5505 - pass external port 80 to internal

[ukdesignated]

I need to allow port 80 through the asa 5505 to an internal webserver.

I have to use port 80 both external and internal due to 3rd restrictions out of my control.

However 80 is a default port.

Can this be done?

Hi,

To open a port on ASA to a specific device on an internal network requires nat and acl configuration.

Create a static nat to map real IP and port with global IP and port.

Depending upon the asa version make sure that you have appropriate IP allowed in the acl. Pre 8.3 global IP should be allowed and post 8.3 real IP should be allowed in acl.

Hope this helps.
