Iptables Started Problem

Hello there. When iptables is active sites inaccessible.

Which ports need to add iptables

[Igor S.]

Hello.

If you using Apache only, you shall open ports 80 and 443 .
If you using CSF (which was installed by default) all need ports is open.

Try this once your server is booted:
iptables -I OUTPUT -p tcp --dport 2030 -j ACCEPT

make sure you had port for varnish port 80, for ssl port:443,for nginx port 82,and apache 8181
if did not installed varnish and ngnix simply open your port 80,443 this will work
