I would suspect that your NAT box does not like/handle receiving traffic for 
its external IP from the internal network and thus the reply does not go 
through.  Now, I would suspect that your setup works anyway (run gnunetd and 
gnunet-stats, look at the number of connections you get after a couple of 
minutes).  So unless gnunetd fails to connect, the setup is probably 
perfectly fine even if gnunet-transport-check fails (the tool can only be 
used to test the simple cases, it can not be used to rule out problems, and 
gnunet-transport-check can also fail when everything is working just fine).

We should probably at some point write another test tool that uses some 
external machine to verify the network configuration, that would be more 
meaningful.
