Hi,
i am behind a NAT-Router too, having the same problem.
I opend port 8030-8040 for incoming calls in the router.
I tried to transfer a file to a friend but nothing happend as
described in the other posts....
I went to the router logfile and found this :
Unrecognized access from xxx.xxx.xxx.xxx:3594 to UDP port 8030
or
Unrecognized access from xxx.xxx.xxx.xxx:3597 to UDP port 8030
or
Unrecognized access from xxx.xxx.xxx.xxx:3600 to UDP port 8030
so i opened port range 3590-3600... Same result, it will not send
the file ...
