Chapter 6 Advanced Setup
Dynamic Routing
Selecting Dynamic Routing in the “Advanced Settings” screen generates the
“Dynamic Routing” screen.
If a gateway is set up behind the Modem in the network configuration, consult the
documentation that came with the gateway to see what kind of Dynamic Routing
is required, then select the needed option.
NAT (Network Address Translation)
Selecting NAT in the “Advanced Settings” screen generates the “NAT” screen. The
Modem’s basic firewall security is based on NAT. Disabling NAT allows the com-
puters connected to the Modem to be accessed by outside parties. Do not turn NAT
off unless instructed to do so by the ISP.
