I have a vague recollection that you can't do both PPPoE
and IPSec VPN with the same interface. Do you have a
working PPPoE-VPN site?

Bah, I was wrong. The issue was with PPPoE and PPTP-VPN.

I don't see anything obviously wrong with your configurations.

The only thing I do notice at the moment is that for AES, group 5
is recommended instead of group 2.


:isakmp key ******** address 0.0.0.0 netmask 0.0.0.0

You might want to specifically add no-xauth no-config-mode
to your isakmp key lines.

What does no xauth and no-config-mode do? Also is group 2 unsecure?
