Hmm for me.. the UPnP is mapped but the NAT-PMP is unable to get mapped.. Dunno if this really affects much though.. [21:37:45] UPnP: Mapped port 35434 -> 192.168.15.100:35434 [21:37:50] Unable to map NAT-PMP Port. And for me I always used Random Port, and usually did this by actually hitting 'Random Port' and never had any problems with it until I tried out 1.7. So not too sure what is going on.. and yes I have done more auto/manual forwarding of ports to my router and never had any problems with 1.6.1, most came from the beta, and even when I revert back to 1.6.1 I get problems, so I sticking with the latest beta.
