<p>Thanks STE,</p>
<p>But that didn't work. I used already FCDN in all configuration files. Only in Regions.ini I get an error message when I use FCDN. It only allow me to put in IP addresses...</p>

<div>I have used an FQDN everywhere in Sanctuary's configuration, for many years now. Basically, the rule of thumb has been that you either have to use IP addresses everywhere, or use an FQDN everywhere, because OpenSim does string comparisons in places where you might expect an IP address to get resolved first, except that it doesn't. In other words, in a comparison, it will, for example, not consider 65.78.40.167 to be the same as <a href="http://sanctuary.homelinux.org" target="_blank">sanctuary.homelinux.org</a>, even though they are equivalent. </div>

<div>I do not, however, do split DNS, so I can't speak to that. I do run my grid behind a firewall, with no issues, though. </div>

<p>I hope this problem can be solved. I am owner of SIMVALLEY (<a href="http://www.simvalley.nl/" target="_blank">http://www.simvalley.nl</a>) and are running my grid behind a FW. Since I started SIMVALLEY more the 6 years ago I had always put the IP address in as ExternalHostName. I have seen more questions in the past about this but dont remember to see a solution.</p>
<p>I am running split DNS so it is for security reason more handy to use FCDN in the Regions.ini then IP addresses. Is it possible to implement in the next version the Full Qualified Domain Name instead of the IP address?</p>
<p>It will help a lot and makes running a grid behind a FireWall and Split DNS much more easier and confirm the way other services are used on the Internet.</p>
<p>With regards,</p>
