Action
Click the drop-down menu button and select the translation action for this NAT rule:
No Port Mapping = Translate addresses for packets with protocols that don’t use ports and thus don’t
involve port mapping (default). For example, this action supports
ping, which uses ICMP.
Map TCP/UDP = Map ports within outbound TCP and UDP packets to dynamic ports (49152 to
65535) on the public IP address, and vice versa. This is the most common type of mapping. It allows
most applications, including Web browsing, to function through NAT.
Map TCP = Map ports within outbound TCP packets to dynamic ports (49152 to 65535) on the public
IP address, and vice versa.
Map UDP = Map ports within outbound UDP packets to dynamic ports (49152 to 65535) on the
public IP address, and vice versa.
FTP Proxy = Provide FTP proxy server functions and map outbound ports to dynamic ports (49152 to
65535) on the public IP address. FTP requires specialized NAT behavior; this action allows
outgoing FTP transactions to function properly.
