9-6 User’s Reference Guide
When using numbered interfaces, the Netopia Router will use its local WAN IP address and subnet mask to
send packets to the remote router. Both routers have WAN IP addresses and subnet masks associated
with the connection.
6. If your ISP uses unnumbered (system-based) routing, select Remote IP Address and enter the IP address
your ISP gave you. Then select Remote IP Mask and enter the IP subnet mask of the remote site you will
connect to.
Note: When using unnumbered interfaces, the Netopia Router will use either its local Ethernet IP address
or its NAT (Network Address Translation) address (if so configured) and subnet mask to send packets to the
remote router. Neither router has a WAN IP address or subnet mask associated with this connection. These
default addresses will request that the remote router dynamically assign an address at the time the
connection is made.
7. If you entered 0.0.0.0, when your Netopia R5000 Series Router connects to the ISP, the remote router
assigns your Netopia R5000 Series Router an IP address that external users use to communicate with your
network.
The following Quick View screen shows an example in which 192.168.100.6 is assigned to the Netopia
R5000 Series Router. “NAT” indicates that the address was assigned dynamically by Network Address
Translation.
