I just installed ufw on the server. It works so good webpages don't load, ssh is very slow and I can't login to mail, other than that it works really good. I think the online tutorial to install it is leaving out most of the steps needed to actually make it a useable firewall. I think there is way more to configure then just allowing ports. Could someone tell me what else I need to configure and some examples would help?
Here are the ports that are allowed.
21/tcp
25/tcp
53/tcp
53/udp
80/tcp
110/tcp
143/tcp
443/tcp
xxxx/ssh
