IPSEC in GNS3 with SDM

Hi there,

I can't found what's wrong with this situation...

I'm trying to set up a IPSEC between 2 routers with serial interfaces in GNS3.

Interfaces are up, my crypto configuration is correct, firewall/NAT/Routing is correct, but my tunnel status is down and I can't ping the other side, I was able to do this before the config of ipsec.

So, what is my problem ?
