Why, after installing\removing Kerio windows route 6, did the second network card stop letting me connect to the Internet?

Question

Kerio

The scheme is like this. Comp (gateway to the Internet) running WIN7 prof x64 has 2 network cards. One is connected to the provider (Beeline, l2tp connection), the second looks into the local network. The built-in Windows brandmauer is disabled. Lokalka all on static addressing. Before installing Kerio, everything worked fine. I installed a trial version of Kerio 6.7.1 (didn't break it, didn't perform left activation), tinkered with it and demolished it. Now there is no access to the Internet from the second network card (which looks into the LAN), the Internet works on the gateway itself.
The connection settings on the gateway are restored as they were before installing Kerio. There are no other software products (Firewall, Ativir, etc.) working with the network on the gateway. It still doesn't let me connect to the internet. If you ping from a machine from the local network to the local network interface, it pings, and the interface that looks at the Internet no longer sees it. Tell me where to dig in the WIN7 settings? Where could Kerio leave a stub?

Answer 1

and what does kerio have to do with it?) you turned off ics. Kerio informed you about it during installation.
