Pros: I had absolutely no problems setting this thing up with a DSL line & a cable line (DSL dynamic IP and cable has several static IPs). Clearly, I am getting throughput on both channels. When I'm doing only one thing (surfing, or downloading) I don't notice the speed difference particularly. But, if I'm downloading a couple of things, someone's using my external-facing slingbox, etc. --- I'm still able to open an SSH connection & type without each character delaying.

Cons: The only con I can see is that the manual is good for basic setup, but they really need to expand & give sample configurations for the various advanced settings. It's quite easy to get confuseed between virtual server port forwarding, the host tab, a version of the host tab offered underneath the Basic-side menu, the multi-DMZ (which can still be modified on an individual port or group level by the firewall settings, which are under the Filter tab), then the NAT alias feature. Some things conflict with each other, others are complimentary, some are outbound/inboud only, some require bonding to only one of your WAN ports. They really need some sample configurations & better explanations (for example, running DHCP to a couple of a systems, but then having some systems be static, or running a 2nd router behind one port and the others being DHCP). Overall though, a quality product -- and I did not need to upgrade the firmware or download any software. Also, they offer free tech supp
