I currently have IPSconfig installed and working but have some questions as to if I have things set up in the best way. I have cable internet access to my home with 5 useable ips. The cable internet access comes into a cable modem/router (i have no access to this router it is the cable companies). The router has 5 ethernet ports on it. I have one cable going from the modem/router to my Linksy box and then I have my internal home network (192.x.x.x) work just fine. The ISPConfig server is actually on a Microsoft Virtual server with two nics. THe ISPConfig/CentOS server is assigned a nic that is plugged directly into the Cable modem to get one of the 5 usable ips. My question is do i need some sort of additional Firewall or is the firewall that ISPConfig has sufficient? Additional Questions --On step two of CentOS 4.6 Server Setup: LAMP, Email, DNS, FTP, ISPConfig (a.k.a. The Perfect Server) if my current set up is correct i am assuming i need to apply my external IP vs. the way it is documented in the set up.

If i have ISPConfig installed and working properly. Is there any issues with following the set up for DKIM With dkim-milter to implement Postfix DKIM? I think that is all for now. I want to give kudos to all that contributed on the how to's this is a great forum to teach folks...
Normally the ISPConfig firewall is sufficient. You can use the public or private IP address in this case (where your server is in a LAN). This is correct. It means that only localhost can send without authentication. All other hosts must authenticate. Haven't tried DKIM yet, but I *think* it should be no problem.
