Using Provider access for Internet connexion.
Impossible to ping a remote workstation through a IPSec tunnel, VPN seems to be correctly established (show crypto isakmp sa --> tunnel created)
If i replace the Internet network with a router, every thing works fine, tunnel goes up and i can ping the workstation to the othe side. router is configured with public ip address given by the two providers.
To resume, with a router simulating the Internet network --> it's OK
When using real Internet Network --> tunnel goes up but impossible to pass data traffic on it.
