When Setting up OpenVPN UDP on Port 443 I Receive this Error Message "Error The specified 'Local port' is in use. Please select another value"



  • I want to set up my OpenVPN Server for UDP on port 443 and " I then change the port for the webconfigurator from 443 to 8443 (which accessing the pfsense webpage on https://192.xxx.xxx.1:8443 works properly). However I still receive the message "Error The specified 'Local port' is in use. Please select another value". How do I find out what is bound to port 443? I check the firewall rules and could not find anything else bound to 443. Any suggestions.



  • The firewall GUI??



  • Forget about it, I figured it out. I had to change the interface from WAN to LAN. I am too dumb.
