I am trying to configure my linux server to use Iptable as I have just upgraded it from RH6.2 to RH7.3.
It is at the moment driving me nuts. The computer it just an internet router and all I need it to do is handle IP masquerading with active ftp.
Does anyone know a good tool to configure the firewall or a good sight to go to that has rulesets that can be adapted? I am not worried about a secure ruleset I just want one that works!
