I have a domain 'mydomain.com'. I have several web/mail/ftp servers in the cloud on different IPs from different cloud providers:
ftp.mydomain.com mail.mydomain.com www.mydomain.com
I also have a small home/office network with two computers. I would like them to be reachable over the internet:
I have added the public facing IP of my home router to the nameservers as an A record for both home1.mydomian.com and home2.mydomain.com.
What I would like now is to have the home router route incoming traffic to the correct machine but not using port forwarding. I want each machine to keep its own firewall, not just only accept traffic on one port.
