ISPConfig3 Open ports to a specific IP
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!
