[QUOTE="TairikuOkami, post: 784588, member: 61892"] Chromium based browsers call home via port 5228 and 5222 (also Google Sync). So block those, if you are concerned. I use Yandex Sync, so I have port 5222 allowed, but only to Yandex IP range. My allowed rules, the rest is blocked: [CODE]netsh advfirewall firewall add rule name="Yandex DNS" dir=out action=allow protocol=UDP remoteip=156.154.70.2,156.154.71.2 remoteport=53 program="Z:\Yandex\YandexBrowser\Application\browser.exe" netsh advfirewall firewall add rule name="Yandex DNSS" dir=out action=allow protocol=UDP remoteip=194.132.32.32 remoteport=443 program="Z:\Yandex\YandexBrowser\Application\browser.exe" netsh advfirewall firewall add rule name="Yandex Sync" dir=out action=allow protocol=TCP remoteip=213.180.193.0-213.180.193.255 remoteport=443,5222 program="Z:\Yandex\YandexBrowser\Application\browser.exe" netsh advfirewall firewall add rule name="Yandex TCP" dir=out action=allow protocol=TCP remoteport=80,443 program="Z:\Yandex\YandexBrowser\Application\browser.exe"[/CODE] [/QUOTE]
