I'm sure this is obvious to people, but just in case it is not:
I pay $25/month for my VPS, and I think I could bring that down to $10
or $15 if I wanted. My VPS routes me a /48 IPv6 network...
I clearly meant "My VPS _provider_ routes me...".
Before I essentially echo back what Stuart said, let me clarify
something. I don't really recommend NAT over NDP proxying more than the
other way around. I was merely stating that a hack is a hack is a hack.
If you are forced to use a hack, then insisting on one over the other
is bizarre unless on

Summary of this email:
1. I respond to a couple of specific points made by other folks in this
thread to clarify what I'm trying to accomplish (set up a couple of
ad hoc link-local routes without having to ask my ISP for a larger
subnet) and to acknowledge that I said something stupid abo

I don't doubt this is typical for serious network operators. But I
would counter that for every user who is in a position to r
Yeah, I don't have the interest to get into it about this; but I find
it (informally) inconsistent to take an ideological stance against NAT
and not have a similar stance against NDP proxying. Networking is a lot
cleaner when it can be reasoned about with a rudimentary grasp of graph
theory where

Summary of this email: I repeat my argument that automatic NDP
proxying is the right way to handle the "road warrior" use case for
IPv6. The reasons I'm pushing this so hard are that (1) including this
functionality in iked would be much more robust than any hacky script I
could write that tries to
First, thank you! The "ndp -s" trick does exactly what I need. (I did
not need to consider ndp-reflector.) The rest of this email could be
summarized as "That works so perfectly I would pay for someone to make
it automatic; meanwhile the other things I asked about were in fact
bad ideas and I wil
While I suppose the /64 your VPS provider gives you is "enormous"
compared to IPv4, I don't find such a comparison relevant since IPv6
and IPv4 are entirely different protocols. In fact I actually think it
is small. Why? RFC 6177 (https://datatracker.ietf.org/doc/html/rfc6177)
recommends that /48

OK, I've sorted out my network issues server but it turns out that I
was misinterpreting the tcpdump output on my VPS. When an external
computer tries to ping my client's virtual IP address, the VPS's
gateway router is *not* forwarding the pings to my server where they
can be shoved into the IPsec

Short version:
I'm trying to set up a "road warrior"-style VPN like the one described
at https://www.openbsd.org/faq/faq17.html but I'm trying to use IPv6 so
I can have globally-routable addresses (so I'm not using NAT). So far
