Chapter 9
Static Route
9.1 Introduction
If you subscribed multiple public IP addresses (i.e. a subnet allocated by your
ISP as opposed to just a single public IP address), you can set up the router's
second IP address on your first allocated public address. The rest of your ISP
allocated subnet will then be passed through to your LAN.
You shall manually set the TCP/IP properties of PC on the LAN. After you
assign the PC with one of your public IP addresses, you must also specify the
nd
default gateway to the PC (the router's 2 IP address) and some DNS server
addresses (your ISP can advise of these addresses). On your LAN, you can
mix NATed IP addresses and public IP addresses. Consequently, some
PCs really have public IP addresses but some PCs are on your private
(NATed) subnet.
Static routes in your Vigor router provide a quick and effective way to route
data from one subnet to different subnet without using the Routing
Information Protocol (RIP). Basically, a static route is a guiding path in the
router that specifies how the router will get to a certain subnet by using a
certain path. If you have many private subnets behind the router, or you
want to access another public subnet via an inside router, you can configure
the router to route IP packets to those inside IP networks using 1st IP
address/subnet mask fields on the LAN TCP/IP and DHCP Setup page.
