root at tao[~]# ifconfig gif0 inet6 2a01:348:6:45c::2 deprecated
root at tao[~]# ping6 ipv6.google.com
PING6(56=40+8+8 bytes) 2a01:348:294::1 --> 2a00:1450:8002::93

Perfect! That does exactly what I wanted. Traffic is sourced from the
other IP address now. Thank you for this. I was about to try and apply
the patch that you posted but this does the trick.

Regards, Matt.
