Link: Default Server

This feature allows you to:

•Direct your Gateway to forward all externally initiated IP traffic (TCP and UDP protocols only) to a default host on the LAN.

Enable it for certain situations:

–Where you cannot anticipate what port number or packet protocol an in-bound application might use. For example, some network games select arbitrary port numbers when a connection is opened.

–When you want all unsolicited traffic to go to a specific LAN host.

•Configure for IP Passthrough.

Configure a Default Server. This feature allows you to direct unsolicited or non-specific traffic to a designated LAN station. With NAT “On” in the Gateway, these packets normally would be discarded.

For instance, this could be application traffic where you don’t know (in advance) the port or protocol that will be used. Some game applications fit this profile.

Use the following steps to setup a NAT default server to receive this information:

1.Select the Configure toolbar button, then Advanced, then the Default Server link.

2.From the pull-down menu, select Default-Server.

The NAT Server IP Address field appears.

3.Determine the IP address of the LAN computer you have chosen to receive the unex- pected or unknown traffic.

Enter this address in the NAT Server IP Address field.

4.Click the Submit button.

5.Click the Alert button.

6.Click the Save and Restart link to confirm.
