I have a server with only Centova panel, which ports should I set? you could post an example of your configuration?
how was your setup?
# Allow incoming IPv6 TCP ports
TCP6_IN = "20,21,22,25,53,80,110,143,443,465,587,7000:9999"
# Allow outgoing TCP ports
TCP6_OUT = "20,21,22,25,53,80,110,113,443,7000:9999"
# Allow incoming UDP ports
UDP6_IN = "20,21,53"
# Allow outgoing UDP ports
# To allow outgoing traceroute add 33434:33523 to this list
UDP6_OUT = "20,21,53,113,123"
