Re: server IP with vps behind nat

Hello,

most important (as far as I got from you) in the usage of Keyhelp regarding to DNS with an IP-address according to RFC-1918 ("private address") behind NAT is that you lose the public functionality of the Nameserver.

Of course there are options making this work, but its not worth the effort and depends on the infrastructure you use.

Keyhelp will work with close all functionality behind NAT. As long a public nameserver is used to all the domains, provided at the VPS with Keyhelp.
It can be your own public nameserver or of some provider. You just need to point all relevant domain records to the public IP where you proceed NAT to.

Basically Keyhelp and the configured services operation directly with an assigned public IP-address. Not behind NAT. But as explained and many of our users also operate Keyhelp behind NAT e.g. in testing/development enviroments.

In short: Use external DNS-nameservers for the domains @$Keyhelp-Host and Keyhelp will mostly work in NAT infrastructure.
Mit freundlichen Grüßen / Best regards
