9 But what about connecting to the outside world? For that, the
10 link-local address doesn't work. If I'm relying on the router to
11 rewrite the source address for such connections, I'm already doing the
12 equivalent of NAT, and IPv6 was supposed to do away with those :-P

22 I knew about LDP, but I thought I needed some gentoo specifics, such as
23 the conf.d/net syntax. You answered that and thanks. Still, I feel I'm
24 floating in an exoplanetary orbit. No configuration needed for this ULA
25 thing? How does it happen, then - is it implemented entirely in the kernel?
