So as an 'IT guy' I've had to replace routers where for many different reasons being able to login and look at the original settings isn't possible. In these cases what I do is run an IP and port scan of the most common subnets and then investigate which services are actually used by temporarily inserting my laptop as a man in the middle and capturing the packets while certain activities are triggered (flipping switches, blinds, etc), and then I have a pretty good idea of what needs to talk to what and how. It's easy to setup a new router with all essential port forwards and settings after you have a proper map of the network, unfortunately most IT guys will just assume things and not be that thorough..
Another alternative, pick up the phone and call me to see what could be screwed up. Like I said, my number was on the router
