Indeed. The only downside of 6to4 is that your subnet prefix changes with your public v4 address. If you don't have a static v4 address, then it'll be a bit less interesting to do, IMHO. Of course, by properly setting up mobile IPv6 extensions, you could sidestep this issue and get the best of both worlds; but since mobile IPv6 requires a kernel patch and (IIUC) a working IPsec setup, this is too much of a PITA to set up currently, I think. -- The amount of time between slipping on the peel and landing on the pavement is precisely one bananosecond -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
