Be aware!  gminer 2.67 trying to connect 3rd-party IP - 81.4.110.148 at start. If you will try to deny this connection with Firewall -  miner will not start. I've opened issue on the official github page, but still no answer from devs.
It's not devfee pool IP. It's some unknown suspicious IP to which private information can be transmitted from your PC.
p.s. Gminer 2.66 works perfect with block all ip except of my Pool's IP.
