Re: Inside / Outside network access

0 comments
Assuming the router you use supports it, a DNS service like DNSMasq
(http://en.wikipedia.org/wiki/Dnsmasq) should handle IP translation
and forwarding of any domain name, including internal ones. (tomato,
dd-wrt and pfsense all use it)

What we do is issue each of our clients their own domain name, a sub-
domain of ours: <clientname>.ourdomain.net. The client's router
updates their domain name public IP through the DDNS service. If your
router uses DNSMasq or a similar DNS service (http://en.wikipedia.org/
wiki/Comparison_of_DNS_server_software
), it will know how to properly
translate and forward the IP for <clientname>.ourdomain.net for any
ipod/iphone/ipad running CF regardless if it on the local network or
remotely over the internet.

The domain name is placed in the CF program instead of the internal
LAN IP of the Crestron processor or public IP of the modem. No need to
have to change an IP address again.

Hope this helps,
Eric
