Re: [Home Network] Access my network from out of area. SOLVED!

You can use a free dynamic DNS service and then set a CNAME on an existing domain with an existing DNS service.

I could never get this to work as the CNAME is "out of zone" data.

I have gotten cross domain CNAME to work using an external DNS provider, but since many DNS forwarding providers are now implementing DNSSEC (as AT&T and Comcast are both doing), such cross domain DNS tricks may not work for all users anymore (especially for the primary domain name record, as opposed to subdomain records).

You aren't supposed to use a CNAME for the root domain, only A record (supplemental records such as MX, TXT, etc are fine too)

Yes, I know that it has never been a recommended practice, but until recently when DNSSEC started to be used by mainstream ISPs, it had always worked (for many years). It was very handy if you had multiple domain names sharing the same web site (for example, my nature-pics.com, wild-life-pics.com, and wildflower-pics.com domains all share the same web site), and also had a backup web site for times when the primary site might be down (server failure, ISP failure, fat-finger failure, whatever). All I had to do was to change the primary A record for the "main" domain name, and all of the CNAME domains would still point to the main domain's currently active web site. Now, I have to change multiple domains when that happens. Not a biggy, but life was simpler when I could just use CNAMEs for the related domain names and only have to make one DNS record change.
