I got two domains, which are pointing on the same IP address, I can use both to connect to the server or certain port (TeamSpeak), the problem is that I would like the only one domain from those two to be working while connecting to a certain port.
Eg.
example.com
points at the 11.22.33.44
-- allow connection to the certain port from this domain.
sample.com
points at the 11.22.33.44
-- disallow connection to the port specified above from this domain.
I know this would be possible for the IP addresses, but would it be possible for the domains?
