Yes, but unless that ipv6 that isn't globally routed is NAT66 to the outside world, then it wouldn't have external access.

Inbound, if on the inside, you're using IPv6 space that's not globally routed, won't. Just like what happens now with NAPT with rfc1918 space on the inside when you stop doing translation...private IP traffic leaks out...but nothing comes back because there is no return path. ---------------------------------------------------------------------- Jon Lewis, MCP :) | I route Senior Network Engineer | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________
