Just a quick follow up to say that it is all working fine after I
upgraded to version 2.4.9 of pppd.
I had initially been using version 2.4.7, that came with Raspberry Pi OS
(buster).
I had also been testing using git master of the ppp repo on the 'client'.
But I hadn't tried upgrading the 'server' (the peer configured with the
interface identifiers).
After upgrading to 2.4.9 on the 'server' it works perfectly - even with
an older version of pppd on the 'client'.
I haven't tracked down the commit that fixed it but I guess it was
something to do with failing to Nack the random interface identifier
sent by the peer.
Thank you for your help and thoughts on the issue.
nick.
