Link: Default Server
This feature allows you to:
•
Direct your Gateway to for ward all externally initiated IP traffic (TCP and UDP protocols only) to a default
host on the LAN.
Enable it for cer tain situations:
– Where you cannot anticipate what por t number or packet protocol an in-bound application might
use. For example, some network games select arbitrar y por t 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 por t or protocol that
will be used. Some game applications fit this profile.
Use the following steps to setup a NAT default ser ver 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 Ser ver 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 Ser ver IP Address field.
4.
Click the Submit button.
5.
Click the Alert button.
6.
Click the Save and Restart link to confirm.
