I am using Serv-U 6.4.0.6. My antivirus log shows it is blocking occasional attempts from Serv-U to communicate on ports 6666-6669 (outgoing). This is suspicious because those ports are often used by malware. Is this behavior normal?
Most recently, it has been trying to reach 76.8.210.66 and 70.99.186.222 on those ports.
