Viewing And Modifying Gateway Settings - Novell ACCESS MANAGER 3.1 SP1 - GATEWAY GUIDE Manual

If your Access Gateway isn't performing as expected, check to ensure that the duplex
settings for its network adapters match your network configuration. It might be necessary
to manually configure the duplex settings on both your Access Gateway and your Ethernet
switch or hub.
NAT: Select Dynamic or Disabled.
If the Access Gateway is serving as a router, and your network employs non-unique
private IP addresses, you can configure the Access Gateway to provide Network Address
Translation (NAT) services.
For example, if you have a 10.0.0.0 private network on eth0 and a registered public
network such as 130.0.0.0 on eth1, the clients on the private network can access the
Internet through the Access Gateway, provided that the Dynamic option is selected in the
NAT drop-down list for the eth1 adapter.
The Access Gateway then functions as a network address translator and dynamically maps
the private, non-routable 10-net addresses to the registered public address assigned to
eth1.
IMPORTANT: You cannot configure a reverse proxy on an IP address assigned to an
adapter that has the Dynamic option set for NAT. NAT and a reverse proxy cannot coexist
on the same adapter.

3.8.2 Viewing and Modifying Gateway Settings

The gateway settings display the current gateway configuration that the Access Gateway is using to
route packets. On this page, you can also configure additional gateways. During installation, you
could specify only a default gateway. You must have at least one gateway defined for the Access
Gateway to function.
The Access Gateway routes requests to specific destinations through these gateways. If a request
could be routed through multiple gateways, the Access Gateway chooses the gateway associated
with the most restrictive mask (the smallest range of destination addresses). The default gateway is
used only when no other routes apply.
Gateways fall within the following three basic groups:
Host gateways for specific destination addresses.
Network gateways for destination addresses that fall within specific subnets.
The default gateway for destination addresses that aren't covered by host or network gateways.
The Access Gateway uses additional gateways only when the Act As Router option is selected.
When this option is selected, you can add Host Gateways and Network Gateways. When
configuring a Host Gateway or Network Gateway, you specify the IP address of the host or network
gateway in the Next Hop field. This address must be on the same subnetwork as the IP address for
the Access Gateway.
IMPORTANT: If you enter an IP address that is on a different subnetwork, the Access Gateway
reports this error on the Health page, after the configuration has been applied.
