Q: Can I use the dual WAN interfaces for load balancing traffic? A: Yes you can. There are a couple of methods for doing this. One is to use the built-in Equal Cost Multi-Path (ECMP) routing mechanism offered in version 3.0 MR2 and above. This method uses a simple hash algorithm to automatically balance sessions between two or more equal cost routes. The other is to use policy-based routing rules (available since version 2.8) to manually send some traffic to one port and other traffic to a different port. You can route based on source or destination IP addresses or based on protocol type / TCP or UDP port numbers, or any combination of the above.
