The required ports on servers with CyberPanel installed are as follows. For hardware or software firewalls, opening the port values below is sufficient.
TCP: 8090: CyberPanel management panel port.
TCP: 7080: LiteSpeed management panel port. (I added this in case advanced users need it.)
TCP: 22: SSH default port.
TCP: 80, TCP: 443, and UDP: 443: Ports required for Web Server.
TCP: 21 and TCP: 40110-40210: Ports required for FTP.
TCP: 25, TCP: 587, TCP: 465, TCP: 110, TCP: 143, and TCP: 993: Ports required for Mail.
TCP: 53 and UDP: 53: Ports required for DNS.
