Should the domain.tld be a online domain or can it be a local domain. For instance: can the domain be mydomain.local or should it be mydomain.com?
I have the following setup: ---- WAN ---- Firewall ------- Server 1 (192.168.1.10), Server 2 (192.168.1.11) so I should create mydomain.com with an A record server 1 which points to the wan ip?
