Hi, We recently started using ISPConfig 3 on one of our servers and love it so far. One problem I cannot figure out is how to open a port to only a specified IP address, we would like to access certain ports on the server from within the office, is this possible?. I tried it with IPTables directly, which worked but found that once I changed the ports from within ISPConfig firewall settings that it got overwritten. Thanks in advanced!
Please see here for instructions to add custom iptables rules to the firewall: http://www.howtoforge.com/forums/showpost.php?p=202906&postcount=4
You are posting to a very old and outdated thread and the link you refer to is not relevant for any recent install. Today, ISPConfig uses UFW firewall, and you simply use ufw command to add additional rules.
