NOTE: To connect via LAN, it is necessary to add rules for incoming and outgoing UDP connections on port 18190 (the default application port) to the Windows firewall before configuration. This can be done, for example, by running the command line (CMD) with administrator rights and entering the commands:
for incoming connection:
netsh advfirewall firewall add rule name="KoRC_UDP_port" dir=in action=allow protocol=UDP localport=18190
for outgoing connection:
netsh advfirewall firewall add rule name="KoRC_UDP_port" dir=out action=allow protocol=UDP localport=18190
