Re: How to know if a port is forwarded

[andrewhaynes () clear net nz]

Hi Gustavo
You could try the time difference from a port that would get blocked and one that won't, averaging out over a couple of 
packets.
If you know the IP that its meant to get forwarded to you could try to use routeing packets (source/x-forward) from the 
IP behind the router. If they forwarded it to some other destination it got through, otherwise the router should drop 
it as a bad packet.(having tryed it but might work)
