VLANS across site-to-site not letting traffic to flow between each

[newbutnot]

ASDM user - Configured site=to-site using FP1120 but traffic is not flowing to vlans which are identical other than 2nd octet at both locations. Both crypto map and Profiles are using same encyrtion and NAT exception. But I am unable to ping or rdp anything from site to site. Lastly, there are ACL rules in place to allow traffic. What am I missing?

Both sites have ASA 1120 BTW. I have confirmed the tunnel is up by looking at monitoring/sessions. I can see the tunnel active.

Acl in one side must mirror not must be same'

Are you sure config acl for ipsec correct?

[newbutnot]

When looking at the ACL Manager under Site to Site, I do see differences. Is this what you are referring to? 

[MHM Cisco World]

Can you share acl of both sides?

Unfortunately, not on a forum. But here is an error:

that simple 
you use exception NAT but there is other NAT above it effect the return traffic 
only check the order the order of NAT you config

Hello,

post the NAT rules for both sides (change the IP addresses and interface names if you don't want them to be public).
