To request my IPv6 /64 on my WAN interf= ace I run the following every two minutes, otherwise I lose the address:
/bin/rdisc6 -v eth0

With this v6 works ver= y good and I have no issues at all.

But prefixes c= hange every 24 hours or so

This has

far it has changed = once in the last 2 months). The lease time is
incredibly short, which is= a little strange but as long as the DHCPv6

same prefix upon request.

t= hat forced
openwrt to flush and reload the firewall every minute, or less.

I'd pioneered a stateless firewall in cerowrt that ne= ver ever ever
needed to reload the
rules, using a pattern match for each spec= ifically renamed ethernet interface.

Regrettably that wa= s not accepted into openwrt, because "nftables" was
just around th= e corner.
It scaled beautifully to tons of interfaces going up and down so l= ong
as they were named appropriately,
at far less cpu overhead for complicat= ed rules than the standard
openwrt firewall.

Anyway, I don't remem= ber all that we did to suppress the flood of
useless static changesto everyt= hing ipv6, but I hope that whatever we ended up doing still
works in this ca= se.

I also built a very crude measurement display that just us= es curl get
and dig via smokeping to display reasonable RTT. It's de= tailed in the
reddit post here:
https://www.reddit.com/r/S= tarlink/comments/mykxjv/functional_ipv6_and_some_crude_starlink_latency/
and can be viewed directly here:
https://starmon.qos= box.com/

THX! We really need to collect the "good" i= nformation and publish it
somewhere, the reddit noise level is too high.

One piece of mis-information I think was the news you can &= quot;route"
packets over ipv4 with a box in front of it and
a default gw= of 192.168.100.1 Not clear from that news whether or not
NAT was required= on the next hop or not... ?

= (that's from another re= ddit post I mis-remember)


Making dhcpv6-pd work is pretty = standard:

/ipv6 dhcp-client

add add-default-route=3Dyes inter= face=3Dether2 pool-name=3Dstarlink-ipv6
prefix-hint=3D::/56 request=3Dpr= efix

On each interface you want to have IPv6 on:

/ipv6 addres= s

add address=3D::1 from-pool=3Dstarlink-ipv6 interface=3Dbridge.8
add address=3D::1 from-pool=3Dstarlink-ipv6 interface=3Dbridge.6

THANKS SO MUCH. I am thinking at the moment that openwrt's dhcp-pd=
= implementation is currently
broken (it's not working on admittedly a com= cast modem I just got that
I'd not used before), but
as soon as I get a c= hance I'll try configuring odhcpd6 to do something
like this. If I can r= emember how.
