our customer has a swisscom dsl connection and last week they changed these to v6.
he already tried 3 times via swisscom helpdesk without success.
the first level seems to have no idea about ds lite and v6... ;-/
we want to go back to v4 native.
in customer center we have deactivated v6 - but it is still online via v6 and ds-lite
we did all what was explained:
- switchoff modem for an hour
- reboot 3 times router etc
effectively now the vpn is for sure not working via ds lite and carrier grade NAT....
thanks in advance
Stephan
