I had to configure a DNS forwarder for a .com domain. All machines on green are working fine: when they want to connect to the site they get the right internal IP address.
This site is also available via the internet and the internet address should be used by machines on the blue network.
But because the name resolving results in an internal IP address, the blue machines can't connect.
Is it possible with the dns server from ipfire to resolve a site name to different IP addresses depending if you are on green or blue?
Or should I install a DNS server in blue to overcome this problem.
