Hello,
under your BRI interface you have dialer pool member 2.
That points to interface dialer 2 and I do not see a dialer interface 2 in your conf. Try that and see what happens.

Do the above changes and check the issue..Leave the nat commands configured as it is..

Hello
Change the dialer interface to d2 instead of d1
