Has any one set up iptables for a2billing? I want to restrict outside wan access to only the /a2customer and /a2billing/signup pages ONLY using iptables INPUT chain but cannot find the proper settings or even if it can be done. Can iptables be specific on directories able to be accessed? I have no need for fail2ban as I accept NO SIP connections. htaccess wouldn't help much in my situation either as I don't want LAN security and want public access to just 2 directories on my server for my customers. I also do not want admin wan access, just leave it to local LAN only which is physically secure here. and I do not want to use an external firewall solution, rather have it all on 1 box.
