SFOS v21 - Windows DomainController connection to Clients behind RED recognized as Freegate Proxy

Hey everyone,

today i noticed our Windows DCs want to communicate with Windows Clients behind a RED Device, where SFOS is recognizing it as a Freegate Proxy Application and blocks it

Src IP = Win DC

Dst IP = Win Client behind RED

Seems to be the same as already mentioned in this post: Application Filter false positive - IP whitelist - Discussions - Sophos Firewall - Sophos Community

But in Firewall Logs i cannot see any blocked connections. Dont know if i should allow these connections. Anyone else experienced this behavior? 

Regards

Peter
