We're starting to learn about routers for our small business (10 computers connecting to the internet through a dsl modem). It's difficult to figure out which level of router to buy. We know we need NAT and port forwarding, and that we need to be able to assign a static ip to a mac address. We also need control over the firewall.
The cheaper routers seem to have all the features we need. is there any reason to go with the more expensive ones (stability, speed, etc)?
Also - do we need gigabit ethernet on the wan side if we're using a dsl modem to connect to the internet? how about if we switch to t1 in the future?
