[ FMT Connect Feed] Doug Elder gives all of you FileMaker Server people a few tips on working with DYN…here is the latest from Doug….Once you have your FileMaker Server setup and accessible remotely, I recommend setting up Remote Access service. Their tagline is “Access your device or files using a unique hostname, instead of a confusing (and ever-changing) IP address.” The reason you may need a service like this is because in many cases your Internet provider doesn’t want you to host services on your home or small business line. They will frequently change your network IP address to prevent you from hosting services.

What that means to your users, is that periodically they will have to call you up and complain ‘They changed the IP address again. What is it now?”, instead of being productive. Your Internet service provider (ISP) would rather upgrade you to a business package with a fixed IP address at an additional cost.

Fortunately, as with most things Internet-related, there is a workaround to this issue. For $25/year will assign you a domain name for your server and help you keep the IP address up to date automatically.

What this will look like for your database users logging in remotely is, instead of entering an address like this with an IP address number in it:


They would instead use something like this:


Think of a domain name as a more memorable alias for the user-unfriendly number scheme (IP Addresses) that the Internet is built on.

Once you have the service setup and pointing at your FileMaker Server, you install a free client application called DynDNS Updater from on your FileMaker Server computer. This light-weight software app runs in the background and keeps track of your router’s IP address. If your ISP changes your IP address on you, the software will detect the change and update the remote domain name server. Best of all, no more phone calls from FileMaker Pro users needing to know the new IP address for the Server….
