I'm renumbering a server of mine in order to ease migration and am setting most its services to listen to both the "old" and the "new" IPv4 address. I have a little more problems with the 6to4-serviced IPv6 address: adding an alias to stf0 doesn't seem to work, probably because the internal sanity checks use only the first address and don't know about the alias I added (thus this could probably be solved closing kern/123858 but I didn't yet try that); I then tried (unsuccesfully) to have two different 6to4 interfaces, which should IMHO work: % sudo ifconfig stf1 create ifconfig: SIOCIFCREATE: Invalid argument I guess the kernel is hardwired to support only one stf interface? BTW: that server is a 6-STABLE. "man stf" states: Each stf interface is created at runtime using interface cloning. This is most easily done with the ifconfig(8) create command or using the cloned_interfaces variable in rc.conf(5). -- Lapo Luchini - http://lapo.it/
