I have the following problem: when creating a network through a router, the computers cannot see each other. Yes, I know it's a common issue, but I haven't found a solution yet. How can I configure the router so that I can play both through Hamachi and on a local network? I have ESET installed, and it doesn't interfere – this has been confirmed through experience. Firewalls are disabled, and both computers are running 64-bit Windows 7. The computers meet the system requirements. It's possible to play on a local network, but then there will be no internet access (this happens when you enter the internal IP address in the network settings on the computer). It's also possible to play through Hamachi, but only by unplugging the cable from the router, i.e., connecting directly. Please help! I suggest creating a dedicated thread so that people don't have to ask the same question repeatedly.
