Gateway Configurations

In gateway mode, wireless users are provided additional firewall
protection from the rest of the industrial or shipboard network or Internet
using Network Address Translation (NAT) protocol features and firewall
options.
Wireless users can still communicate with the wired network resourc-
es but communication must be initiated by the wireless devices. Using the
NAT protocol, the only IP address visible to the wired network is that of
the gateway itself, as assigned by the wired Ethernet DHCP server. The
gateway provides firewall protection to its wireless users. It can dynami-
cally assign private addresses to member devices using its own internal
DHCP server. It acts as a router, not a bridge, and controls traffic flow and
access control between the wired and wireless networks.
