Thanks to Jan 'RedBully' Seiffert, dnsmasq now has IPv6 support in the TFTP server. To use this, you'll need a client which also knows about IPv6, I found that current versions of tftp-hpa do. A test release with this functionality is available at: http://www.thekelleys.org.uk/dnsmasq/test-releases/dnsmasq-2.56test4.tar.gz Cheers, Simon.
