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 4200
so that external hosts can reach the web server.
Each entry should be placed on a new line.
C. Press Submit.

Static IP routing
In addition to locally connected IP networks the 4200 can forward traffic for one

the remote data network will be forwarded to the specified gateway address in the
entry.

the gateway. The hosts portion of the

F. Enter the Netmask of the remote data
network. For example, 255.255.255.0
G. Enter the Gateway IP address of the
interface that will receive all packets
destined for the remote data network.
