1. New rule in "Firewall -> Access Rules"



Figure 1

2. Click "Server Mangement" to define new services ports. This router does not allow you to define udp ports 443-65534 in a service because UDP 1701 already exists. So we need to define two services.

New service on udp ports 443-1700



Figure 2

New another service on udp ports 1702-65534

3. Add two deny rules

Please notice:

  1. There are two ACL rules on two services.
  2. Choose "Action" as "Deny".
  3. Choose "source interface" as "Lan", "Destination" as "Any".
