Easy VPN between 5505 and 3030 tunnel build no traffic

Hi,

I have 3030 which is setup for accepting easy vpn connections with IPSEC/UDP.

When i setup a 5505 to connect to this 3030 with easyvpn it works perfectly from my lab (asa is connected to a router to simulate a broadband connection) and then goes on to the internet segment where the 3030 resides.

This setup works perfect.

When i place this same asa on a DSL connection a tunnel is build and all looks fine, but I'm unable to ping back and forward, i can only ping the public of the 3030. I have the same problem on 2 other sites going back to the 3030 which worked fine from my lab.

I'm suspecting a mtu issue but I'm unable to discover how to troubleshoot this.

Is DSL modem configured in bridged mode?

Check if your DSL modem supports vpn passthrough, make sure it is enabled

this device does not support bridged but allows vpn passthrough, sometimes it will work but stop working after a couple of hours all of a sudden. Rebooting will not even solve it.
