IPSEC site to site VPN Issues (lab recreating real issue)

Ninjabean

Level 1

I am new to the security world, and am having a bit of trouble.

We are trying to set up a VPN for a customer to a new vendor - and it is quite a complex (to me) design.  They have a DMZ, and basically we are trying to give the 10.2.0.0 remote subnet access to the local 10.1.1.1 machine. In the lab, I am just trying to get the basics and work up from there.

I was able to get phase 1 going, but then phase 2 said it had a mismatch.  I tried to recreate this in packet tracer, and no matter what I do I cannot get phase 2 set up in packet tracer either.  Even following step by step guides, or copying the solution from a packet tracer lab, I cannot get it to work.  

I feel like I am missing a piece - what I have so far, and I have changed this setup many many times just trying to get it work:

 

The attached configs are a lab environment and IPs are not real.

That makes a lot of sense! I have definitely learned a lot throughout this process. Nothing like a trial by fire
