To add a static route to a specific destination IP on the
local network, enter a Destination IP Address, select
a suitable IP Subnet Mask, and type in the Gateway
IP Address. Click SAVE to enter the new static route
in the table below. The route becomes active
immediately upon creation. The Metric field
determines the number of hops or routers that will be
allowed to route traffic.
NAT
The Router features include policy-based Network
Address Translation (NAT) for greater flexiblity and
control of NAT functions. The user can customize port
mapping for a single global IP address or full feature
NAT support for mapping multiple global IP addresses
to servers or clients on the LAN. Single User
Account (SUA) NAT is enabled by default. Using the
default settings, NAT will function for Routed
connections without any additional configuration. NAT
is disabled automatically when the device is operating
in pure Bridge mode.
To customize NAT settings for IP address mapping,
use the NAT window located in the Advanced Setup
directory.
