20. can you please tell us what is the nat access list for this IPsec Tunnel ???..coz when I put nat command between Router 1 and Router 3, It doesn't work. I can,t access the local network.

21. But how to make this on real device? And where should be the location of IPS?

22. I seem to be the only one having problems. I've followed your steps but its seems that R1 or R3 cannot encrypt the traffic. What could cause that? I've re-read all the configs but can't find the issue…
