I'm trying to set up (what I thought to be) a simple IPSec VPN connection between two routers using the loopback addresses as endpoints but I am having big problems implementing it. The tunnel goes from R1 to R3 through R2 and the IGP used is EIGRP. I've attached the configuration files for both routers.
When I try to do an extended ping from F0/0 on R1 to F0/0 on R3, it fails. With a "debug ip packets" on R3 I see that the source of the IP packets received is 188.8.131.52 (Se1/0 on R1).
What am I missing here to make all this work?
Thank you so much
