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 ips except of my Pool's IP.
Why do you have any info on your mining rig?
Rig should only be for mining. As for access to ip its usually for dev pool update / check for miner update.
Do you think that all people mining on 100500gpus? I have a few rigs for mining + Im mining on my work PC, cuz why not? I have 3080ti in it. Well I don't care about my rigs, and I'm care about my work pc, cuz it have important info. As I said, its not pool IP, so it's not for devfee. Next step is updates: Gminer haven't autoupdate as I can see. Looks like a bullshit. 2.67 is first version that won't start with block all IP's exept my pool IP. I used a lot of other mining software, and all of them works perfect with only POOL ip allowed.
