I can't connect from here either. If you have firewalld disabled, see what your firewall rules look like (iptables -L -n -v) - ideally you would have INPUT/FORWARD/OUTPUT with ACCEPT policy, and no other chains defined. Do you have a public address right on your ispconfig server, or also using NAT? If the latter, check your port forwards and firewall rules in pfsense. Check firewall logs there, and see if the HTTP (port 80) or SMTP (port 25) requests are being blocked.
iptables -L -n -v Chain INPUT (policy ACCEPT 1674 packets, 339K bytes) pkts bytes target prot opt in out source destination Chain FORWARD (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination Chain OUTPUT (policy ACCEPT 1736 packets, 815K bytes) pkts bytes target prot opt in out source destination
ok i figured it out after 3 days!! lol my comcast business modem had port management turned on and it was blocked incoming ports. i turned that off. even though i put it in virtual bridge mode so it only uses my pfsense, somehow comcast was causing issues!! finally!! its amazing ispconfig 3 it works great!!
