Well i only suspecting your try to use ipsec, wich is a crazy vpn solution.
I would sugest to evaluate ssl based vpn in the future which naturally do not run into nat problems.

Just my five cents

Hello,


could be someone from swisscom so kind and contact me offlist via email please.

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
