I am not familiar with pdnsd. I will igonre it but someone else might be
able to tell whether it gets in the way.

There should be a /etc/ppp/ip-up.d/00-ipppd that is taking care of the

Are you sure you run the correct commands? Perhaps you can run the
commands in /etc/ppp/ip-up.d/00-ipppd manually one after the other?
Nothing else that I can think of at the moment.

That line is of no relevance here, isn't it?

Isn't your firewall denies desirable connections because the firewall
gets confused about 62.136.208.169, which is actually one of your
interfaces?
