** Description changed:
My connection works in 20.04 and fails in 22.04. Perhaps something i've
been using is now depricated? Or perhaps jammy xl2tpd is...still
working on it?
see my attached syslog extracts at comments #6 and #7. i extracted them
thus:
- egrep "l2tp|swan|ipsec|charon|XFRM|layer 2|\<ike" /var/log/syslog|egrep
- -v "INFORMATIONAL_V1|packet: from"
+ egrep -i "l2tp|swan|ipsec|charon|XFRM|layer 2|\<ike"
+ /var/log/syslog|egrep -v "INFORMATIONAL_V1|packet: from"
what seems to stand out is:
These lines show up in syslog only in 20.04:
Nov 22 06:22:04 e540 ipsec[782]: 12[KNL] 3.i.p.4 appeared on ppp0
Nov 22 06:22:04 e540 ipsec[782]: 14[KNL] 3.i.p.4 disappeared from ppp0

Nov 22 06:22:04 e540 ipsec[782]: 05[KNL] interface ppp0 activated
These lines show up in syslog only in jammy:
