Network Planning for Dual WAN Ports
C-9
v1.0, August 2006
Inbound Traffic: Dual WAN Ports for Improved Reliability
In the dual WAN port case with rollover (
Figure C-5
), the WAN’s IP address will always change at
rollover. A fully-qualified domain name must be used that toggles between the IP addresses of the
WAN ports (i.e., WAN1 or WAN2).
Inbound Traffic: Dual WAN Ports for Load Balancing
In the dual WAN port case for load balancing (
Figure C-6
), the Internet address of each WAN port
is either fixed if the IP address is fixed or a fully-qualified domain name if the IP address is
dynamic.
Figure C-5
Note:
Load balancing is implemented for outgoing traffic and not for incoming traffic.
Consider making one of the WAN port Internet addresses public and keeping the
other one private in order to maintain better control of WAN port traffic.
