2. Create a group to load balance the WAN link routers.
3. Assign the response metric for the WAN link group.
Any of the server load balancing metrics may be used, but response or bandwidth metric is
recommended.
4. Configure health check for the WAN link group.
5. Enable SLB.
Step 3a (Outbound Traffic)—Configure the WAN Link Ports
Configure proxy IP addresses on ports 25 and 26.
Each proxy IP address must be unique on your network.
Step 3b (Inbound Traffic)—Configure the WAN Link Ports
1. Enable client processing at ports 25 and 26.
This enables inbound traffic to access the virtual server IP address.
2. Enable transparent load balancing for ports 25 and 26. Enable transparent load balancing to
ensure the returning traffic from all servers to go back to the same ISP router.
3. Enable WAN link load balancing.
