We are proud to present a limited Dynamic IPv4 Tunneling Support Public Beta program. First come first serve. If you are interrested in participating send the nichandle you are using at SixXS to info@sixxs.net under the subject of "Dynamic IPv4 Beta Program". In the email note your intended use (dialup, laptop), how much your IP will be changing and ofcourse the OS('s) you are going to use. 1 Dynamic tunnel per account btw unless you really have specific reasons. Current tunnels can also be 'converted' from static to heartbeat tunnels. The functionality should be stable but we want to test it in public over the various POPs to test if it really works in the wild. The client programs along with sourcecode will be released after the beta program has finished and possible bugs have been cleared out. Before anyone asks, this will allow for users having Dynamic non-24/7 IPv4 addresses to make use of the SixXS POPs, it could even be used on static IP's, thus when connectity between the POP and the client is severed the tunnel gets disabled, thus costing you no credits :) Currently supported platforms: - Linux - Free/Open/Net BSD others on request... The Windows client is forthcoming but will also contain autoconfiguration support and a GUI. The clue of the functionality is the heartbeat protocol allowing the POP to detect client IP changes and timeouts of which thus disabling the tunnel on the fly. It still requires a public unfiltered IP address, NAT's are not supported at the moment. Ofcourse all SixXS rules still apply.
