server, a mail server or an FTP server. In these instances, the 4300T statically maps
the public IP address of each server to the actual private IP address of the server.
PLEASE note: In order for Static NAT to function dynamic NAT must be enabled.
A. Select NAT.
B. Enter the public and private IP addresses and ports to be mapped in Static
NAT Client Entries using the following format:
Protocol;PublicIPAddress/netmask-port>PrivateIPAddress-port
For example, the entry “tcp;198.66.203.19-80>192.168.1.3-8080” will map all web
traffic destined to public IP address 198.66.203.19 to the private webserver
192.168.1.3 port 8080. The public IP address of 198.66.203.19 is automatically
created as a “subinterface” or “secondary address” on the WAN interface of the
4300T so that external hosts can reach the web server.
Each entry should be placed on a new line.
