This seems to be the same problem as reported by Nicholas Taylor in Question 175914.

"I dug around some and found that this is a bug which was introduced in xl2tpd-1.2.8. Actually it's a bugfix for a bug that never existed.... This version of xl2tpd overrides and ipparam settings in /etc/ppp/$connection.options.xl2tpd with the server you are connecting to.

Debian list talking about it

Solutions are to downgrade xl2tpd to 1.2.7 or wait for a new version. I installed version 1.2.7 from Ubuntu 11.04 and that seems to be working fine. I think this issue should be noted in documentation."

Can you help with this problem?
