Hello, This sounds nice, but will it work at all with a truly dynamic upstream IPv4 interface, i.e. one that is not brought up immediatly at boot-time with ifupdown?
It is my understanding that 6to4 is typically meant for small IPv6 islands with a DSL/cable connection. A typical scenario would be one or more statically configured Ethernet “downstream” interfaces, and a dynamically configured PPP “upstream” connection. In that case, if I'm not mistaken your script will fail because it the IPv4 address of the 6to4 gateway will not be known at the time when the Ethernet interfaces will be ifup'd. Radvd already kind of support this situation with its Base6to4Interface and refreshing with a SIGHUP. But maybe it's hardly possible to support this situation properly. Any idea? -- Rémi Denis-Courmont http://www.simphalempin.com/home/
