My Website and Email are already being hosted by a reliable company. That hosting company also manages my DNS. Everything works perfect.
In my home office, I got the brilliant idea to set up an FTP Server.
I want to put the FTP Server in a DMZ so I purchased a ZyXEL USG 50 Firewall.
The firewall is set up. So far so good.
Now ... for people on the outside (my clients) to be able to connect to my FTP Server, I would like to create an A Record ftp.mydomain.com
that points to this server.
The problem is, my ISP didn't give me a static IP address.
I figure I can just set up a Dynamic DNS (DDNS) account with dyn.com but this is where I get stumped.
If my web hosting company is already hosting the DNS for my domain (my website, my email, etc), how can I introduce Dynamic DNS?
want to use the Dynamic DNS Service for my FTP Server.
Do I have to move ALL of my DNS records over to dyn.com? Is this the only solution?
Or ... can I leave my DNS with my web hosting company, and create some sort of record on there, which in turn points to Dynamic DNS, which in turn points to my FTP server?
