Hi
I have recently finished creating a VPN site to site network but it doesn't seem to be working correctly. Everything that I've done seems to be in order but obviously something must be wrong but I'm not sure what though.
Basically i have 2 site networks, 1 with 3 machines on a 10.30.0.0/24 network connected to a switched that connects to an ASA which then connects to an edge device which is a router. The exact same topology is present on the other side but it uses the 10.20.0.0/24 network etc...
I will post the ASA and edge router configs below also. I appreciate any help anyone can give me on this.

I would just like to point out that both interior networks can ping over the frame relay and past the edge route to the "outside" interface of the destined ASA's.
Thank you for the help! It is greatly appreciated!
