Hi, perhaps especially for german users hawing a Fritz!Box Fon or knowing someone. If you want to use your Fritz!Box to route IPv6 you can get a modification for the original firmware which introduces IPv6 (tunnel + native on lan devices). This modification also supports sendig a heartbeat so you can use the Fritz!Box as a client for sixxs tunnels. You can get the modification at ip-phone-forum.de (german only... sorry). Hope it is ok to post this link.... Oliver
