Default Behind a NAT Router

I have found several older posts on the subject (looks like they are talking about ISP Confg 2 since none of the menu options are the same).

Problem: 1 public IP addres, 2 individual dns servers, how do I get this setup with in ISPConfig 3 (please be specific as to what menu and where as I am still learning it).

Also what about web server, where does that IP go

Im behind a NAT too
I seto n evirtual machine with the pfsense firewall using 2 NICs, then i forward every port / service for the LAN IP inside on the server

I have tested many times the multiple server setup, and always stucked in many problems... Now i`m testing one dedicated server with all stuff, i have some posts with problems like, ftp / webdav / sasl on log, etc... But i`m still trying fix it... Hard without knowledge...

I`m still learning too, but if i`m right the second DNS is useless, usualy the second DNS is for an second static valid IP

Default Nat

In my multi server setup the second DNS server is setup as a mirror, so it should be able to use the same IP. I keep reading you use the same IP as staic for the DNS, hwo that works I have no idea as well no idea where to assign it at. Then what IP addresses you assign to the web service

That doesn't tell me where to put the static IP. Is it just in the DNS zone I create

if your two DNS servers are in the same perimeter (same network) for the outside world is redundant since it will fail anyway if your public IP/Server fails.

for the LAN you can set up one server as a slave for the primary , and the primary should be the one that you forwarded the dns port from your router/firewall

by the way if you have just one public IP , there are some free services out there and they will host for you a slave dns server for the outside world ...one of them is buddydns if i'm not mistaken
