I have been installing and using ultravnc client and server since Windows XP without problems. Now after installing the software on my first Windows 10 PC can only connect to it from another PC in my home network after turning off the Windows 10 firewall. In previous windows versions ultravnc servers apparently made the exceptions in the firewalls automatically. I do not want to keep the firewall down permanently. I searched for a list of programs to grant exceptions but could not find one. How can I solve this problem?
