I have to set up a Microsoft Server 2008 R2 running IIS and Document Management Application. It, as with all our facility computers, is behind a firewall and needs to be accessed from the public side, that is web browser accessible. I considered using IP forwarding through our firewall but found some complications such as having to use a non-standard HTTP port like 8080 which I would prefer to stay away from. Port 80 is already used on the firewall for our main web site, this will be a secondary site and internal server.

So, am looking at Dynamic DNS providers and checking to see if members have personal experience with one that is reliable, preferably free. These are the standard ones I've come across.

no-ip

Dyndns

Thanks for any feedback.

I've used no-ip for as long as I can remember, certainly since 2003. It just works

Thanks Crossy. That's the one I'm most familiar with but no experience with. DynDNS is the other popular one I'm familiar with but no longer free.

afraid.org is great. but can't you solve your problem by using a subdomain prefix?

I need to keep the server autonomous from our main server domain. The main server is our research web server and primary DNS for our domain. The other server, which is behind this same firewall/web server is a government server and will probably need to assign a new DNS entry for it.

Dyndns is still free, but more complicated to get then before.

You have to register for the pro version, you'll need to enter CC card details but won't be charged for 2 weeks. Cancel within the 2 weeks and you'll be allowed to keep one url for free.

There's other alternatives, but there are still for example routers only having auto IP updating for the dyndns servers...

tywais.com is still free, crab that and you'll have a cool name for your server/service

Otherwise as urandom mentioned afraid.org seems good for the job.

Not sure if that would be a conflict of interest or not.

One requirement of course is that the client side can run as a service under Server 2008 and just checked and afraid.org does so will investigate both them and no-ip a bit closer. Have already installed .NET Framework 4.0 so my requirements are set to go.
