Re: DNS beginner question

The "open" ports are simply port-forwarded from the router to my
internal network (NAT). And I only have one public IP.
For me the more important issue is whether DNS would work with private
IP addresses.

Hi Michael,

You'll have to clarify "open" regarding the WEB, DNS, and FTP ports on the
router. Are they simply port-forwarded to the internal servers (meaning
based on service ports) or do you have one-to-one NAT mapping a public IP to
an internal for each server? If it's the latter, and each machine has its
own public IP, then you can simply set DNS to point to each server
respectively:

www.mydomain.com -> publicIP1 -> privateIP1
ftp.mydomain.com -> publicIP2 -> privateIP2

The real question is whether you have a block of public IPs or just one. But
to be honest, you can probably get away with just having a single public IP
and using port forwarding as most browsers (including Firfox and IE)
recognize the "ftp" and "www" subdomains and automatically adjust to that
protocol.

i.e. ftp.somedomain.com will automatically be translated to
ftp://ftp.somedomain.com (ftp.freebsd.org ).
