I used comodo firewall (windows). Rule is:
1: Block all ip
2(more priority) : Allow Ethermine IP
 
As I said 2.66 works perfect with this rules. And 2.67 not, cuz it want to connect 81.4.110.148

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.

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.

Внимание всем кто работает с Тезосом.
В Яндекс. Директе, по запросу "TEZOS", на первом месте висит реклама на фишинговый сайт tezbox.gitlub.io(не gitHub, а gitLub. Уже сообщил в яндекс, надеюсь оперативно уберут)
Так же мой знакомый попался на удочку с прохождением KYC. Каким-то образом попал на фишинговый сайт с прохождением KYC, и там ввел свой SEED.
Так же приходят фишинговые письма от tzscan.info, в которых участникам ICO предлагают активировать свои монеты, при этом запрашивая fundriser e-mail и password, которые по факту для этого не нужны.
Будьте осторожны.
