This is a feature request for something that I have been working around for years.

I live in a couple of locations, due to work and have a couple of friends who i have persuaded to buy Squeezeboxes. As we Swissies are green (or maybe just cheap..) I let everybody connect to my server for music/radio/etc .. this also solves the problem of syncing the whole collection to my other dwellings..

What I wanted to do is have one central Squeezeserver and connect all squeezeboxes to that server. This works fine for all of the squeezeboxes in the house with the server, but the challenge was to get all of the external players to work.

As I and most of my friends use Cablecom (Cable internet) the IP rarly changes (only if you have a power outage for longer than 10mins) after trying out VPN, which requires a PC to run or have some router with VPN capibilities, which usualy crash. As i did not want to invest in Cisco PIX/ASA boxes for VPNing (plus all of that overhead...) I went for a differnt aproach. 

I bought a WRAP device (www.pcengines.com) and installed m0n0wall on it and run it as my main router where the Squeezeserver is. I have set up NAT with rules for every location to only allow port 9000 and 3483 to connect to the Squeezeserver. This works wonderfuly!! Songs start at the remote locations neary as fast as at home.

The only drawback is that when there is a power outage, i have to redo some of the rules. The other issue is that this can not be done with XDSL which dynamic IPs that change every day. 

What would be great is to have the possibilty to enter a FQDN instead of just an IP for the Squeezeserver. This would not solve the problems for XDSL.. but if the "server IP" changes, all of the remote Squeezeboxes would not have to change the IP.

My second request would to have built in security for squeezeboxes. You could then enter a password on the Squeezebox and just NAT all traffic from any location to ports 9000 and 3483..
