[isf-wifidog] Dynamic DNS : The ultimate solution

[Philippe April]

I think you guys are talking about two different things:

Francois' talking about how to have subdomains point to the portal  
page of each venue.
The others talking about being able ot get (easily) to the IP address  
of each venue (the address on the internet).

Am I wrong?

We use VPN's all around to reach the different routers so we don't  
have to _know_ each router's internet IP.

If we needed access to the external IP (for a webcam for example),  
we'd look at the REMOTE_ADDR stored in wifidog's database... But  
since a lot of times we're behind somebody else's router, it's pretty  
useless :)
