We have a Comcast SMC Business Gateway router/modem combo in our office, and it doesn't provide much in the way of diagnostic tools or QoS routing. I want to plug another router with Tomato installed so I can monitor office traffic. This would result in a double-NAT setup.
We're all Mac users in the office, and I was wondering if a double-NAT would interfere with with our AFP file shares or or other common network / internet tasks? I'm aware that it can cause some problems, just not sure with what.
