You could use IPTABLES to just block the connections and see if anything stops working?

Interesting -- I hadn't heard of such a thing before (may well be a standard thing -- the fact that I don't know about it doesn't mean a thing).
This is just the NAT/PAT aspect of the router. Unless specific inbound port/IP forwarding has been setup all incoming connections are dropping as they could be for any internal host within the LAN subnet so unless a connection has originated from the LAN side of the router to the WAN side (thusly making an entry in the NAT/PAT tables) and no port/ip/dmz forwarding is set up incoming connections are dropped.
HTH.
