Manage NAT Routing Type
Your FX4200 uses Symmetric Network Address Translation (NAT) routing by default. Use this section to select the type of NAT for your connection.
NAT Type: Use the dropdown to select the type of Network Address Translation (NAT) for your connection.
- Symmetric NAT (default) is more restrictive. It maps requests with the same source IP address and port number to a unique external IP and port, based on the destination IP and port of the outgoing connection.
- PRC NAT (port restricted cone) maps all requests from the same source IP address and port to the same public IP address and port, regardless of destination.
