Anyway, it is valid to use (obsolete) site-local source address for global destination address. The problem seems that router does NOT send ICMPv6 destination unreachable to the sender. I don't know why, but it SHOULD. I'll pursue that question later. It wouldn't be _sufficient_ since there ar

IPv6 connect() from site-local to global IPv6 address.

2006-05-05 Thread David Woodhouse
I've been using and testing IPv6 on a private network. Machines have RFC1918 IPv4 addresses, with connectivity by NAT to the outside world. They also have site-local IPv6 addresses. There is approximately zero chance of getting corporate approval to have external IPv6 connectivity. Since updating
