6 Configure the Adapter List Options.
These options let you change settings for the network adapters on the Access Gateway to
ensure compatibility with an existing LAN. Modify the default settings only if your LAN
requires specialized adapter card changes.
Speed: Select Default, 10 MB, 100 MB, or 1000 MB.
Duplex: Select Default, Half, or Full.
IMPORTANT: Some network adapter drivers do not correctly detect duplex settings.
This is a general industry problem with Fast Ethernet technology.
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.

2.9.2 Viewing and Modifying Gateway Settings

The gateway settings display the current gateway configuration that the Access Gateway Appliance
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.
