It depends on how the server is communicating the internal port to users. If all references to port 8443 are coming in 30x redirect responses, you can simply enable the Redirect Rewrite option in the HTTP profile assigned to the VIP. This will automatically catch and replace any redirects that include the incorrect port.

 

If you're seeing the internal port in the actual HTML document, as part of URL references to document objects (ex. images, scripts, css), then you'd be best to apply a STREAM profile iRule to replace these.
