Configuring the 4300T

Configure Dynamic NAT

Use Dynamic NAT when you have multiple PCs installed on the LAN side of the 4300T that require Internet or WAN access. Once Dynamic NAT is enabled the 4300T will automatically perform an address translation for all packets to/from the LAN side PCs.

1.From the Configuration Menu select NAT.

2.Use the Enable Lan NAT checkbox to enable or disable dynamic NAT. The default value for dynamic NAT is enabled.

3.Press Submit.

Configure Static NAT

Use Static NAT when a server or PC located in the private network needs to be accessible from the external network. Some examples include a corporate web 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.

Note

In order for Static NAT to function dynamic NAT must be enabled.

 

 

1.Select NAT.

2.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.

3.Press Submit.
