Hi @eva2000 . How to open an PORT in filewall?
Info at CSF Firewall - CentminMod.com LEMP Nginx web stack for CentOS /etc/csf/csf.conf has a list of TCP_IN/TCP_OUT and TCP6_IN and TCP6_OUT comma separated list of ports you want to whitelist. Edit it and restart CSF Firewall Also Getting Started Guide step 4
Yeah well Centmin Mod has to cater to general folks so has more ports opened by default Also read Centmin Mod LEMP stack CSF Firewall default port listing | Centmin Mod Community
