USG20W-VPN UDP Port 500 open
I have a USG20W-VPN that is failing PCI Compliance. The scan shows UDP Port 500 as being open. I checked my NAT and security policy and there are no VPN rules setup. I even added a security policy to deny any traffic from the WAN to Port 500. I am using the expert mode through the web interface. I do not use any of the VPN functions of the router. I am not able to remove the IKE service that uses the UDP 500 port. How do I close this port so I can pass my PCI scan?
Thanks for the help,
