Open Firewall Ports¶
In addition to TCP 80 and TCP 443, LiteSpeed uses UDP 443 for QUIC, which is one of LiteSpeed's most popular features. Make sure that TCP 80, 443 and UDP 443 are open in Firewall Configuration. TCP 7080 is also used by LiteSpeed for its WebAdmin Console, and it requires a username and password to log in (you will set these during installation). You should keep this port open to Administrative IP's only.
