Notes from a customer. (Thank you!)
Notes from a customer, January 2025. (Thank you!)

I've worked out how to make use of AA's L2TP service from OpenBSD 7.6, at least for IPv4. (I'm not yet certain of how or whether IPv6 is possible.) I can first offer basic instructions akin to the "Linux / xl2tpd" section of this page: https://support.aa.net.uk/L2TP_Client:_Linux . These instructions assume that you're not using ppp for anything else on your OpenBSD machine.


while preparing this message that I noticed [https://www.mail-archive.com/misc@openbsd.org/msg179951.html this thread]. Oh well, it seems to confirm that ipv6 is not an option, at least not as of 2021.
