[0] http://codeghar.com/blog/openbsd-network-gateway-on-edgerouter-lite.html I had been trying wide-dhcpv6—even with no firewall rules enabled, it erred out—“no route to host” and some other info. I expected that this had to do with `rtsol` or `inet6 autoconf` not working properly in hostname.em0—but according to your blog post, it was likely a misconfiguration on my part. After Mr Archer’s post, instead of giving dhcpcd a shot I tried isc-dhcp-client—firewall off, it immediately pulled down an ip6 address from Cox. After making some adjustments to the firewall, it could pull down one with it enabled as well. Still have a few things to work out now, but this is a great start! Thanks for the input guys! One question… What would be necessary to bake this functionality into OpenBSD base? IPv6 is pretty ubiquitous nowadays—most ISPs support it, most cloud providers support it—it seems common enough that much of this functionality should just work. I know that “common enough” isn’t a good reason to implement features or functionality, it just seems like a core capability that should be present. When I was researching how to set this up, I found many different ways to do so—some of the information was clearly dated, others not so much. It would be great to have just configure this via hostname.em0 (or whichever interface) and have it work. I’m fairly new to OpenBSD but if there’s something I can do to help with this, I’m happy to do so if it's within my skillset.
