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.
