Sometimes certain router types (I know Linksys' do this) will get corrupted when you adjust the port forwarding, or if you have more than just a couple of ports forwarded for a while. I don't know what causes it and it can trigger at any time. I keep about 10 ports forward entries in my router at any given time and this problem happens to me every year or so even on different Linksys routers. After it happens, flakey things will start happening with connections. The only solutions I know of to fix it is either restoring your router's factory defaults by holding in the reset button (a small hole in the back of the router, which you need to use a pen or something to press) for 10 seconds until the router lights blink and then set your router up again the way it was before, or to try using a different firmware revision for the router (WW-DRT is really cool). If the router is your problem, I think this suggestion is probably your best bet to try first and see if it helps.
