A colleague suggested putting my modem into Transparent Bridging mode and connect the router using PPPoE directly to the DSL provider. Seems to work fine.
Port forwarding works well.
Seems to be able to deal with multiple simultaneous connections (15 devices all doing some bit chatter).
Signal strength seems good.
Config interface is better than other routers I've used.
So far, so good. Seems like a solid device and has a feature set that would let you configure just about anything.
