my server it's not resolving domain/ips

[joximu]

Hi avispa

first: your server is in you local network - so there is only the local ip address to be used - for all domains.

then: dns: I assume you take care of the 2 dns, you create zones for domains with the infor: the domain is hosted on my own external ip address (213.....)

next: your NAT router has to forward all incoming traffic on port 80, 25, maybe 110, 143 and 587 - ftp is a bit difficult... to the internal server...

Then your domain should be reachable from outside.
From inside you maybe have a dns problem - it depends if your pc thinks the website is on the external address or on the internal...

I hope you can understand...
