NAT | Rules
This section of the Manager lets you add, configure, modify, and delete NAT rules. We recommend that
you first configure and add rules, then enable the function. To configure NAT rules, you must first
configure a VPN Concentrator public interface; see Configuration | Interfaces .
You can configure a maximum of 10 NAT rules. A typical system might have three rules:
• Provide FTP Proxy services for all private network addresses.
• Map TCP/UDP ports in packets to and from all private network addresses.
• Translate IP addresses for protocols that don't use ports ( No Port Mapping ).
