Hello Juan,
It is normal that it doesn't work. I tested in my lab by creating a group with the the local and remote subnets of the VPN tunnel; and adding the group to the VPN domain of the "RemoteAccess "community. It was OK but it wasn't enough.
In order to make it work, I had to add the Office Mode subnet (CP_default_Office ...) to the local VPN domain because I was getting the following log :
'Encryption Failure: according to the policy the packet should not have been decrypted'
So I created a group with the local subnet and the Office Mode subnet to be added to the VPN domain of the local site:

Then, I had to authorize the Office Mode subnet, on the remote gateway because the packets finished in the cleanup rule of the remote gateway.

This way from the remote client (on remote access), I was able to access to a PC on the remote site through the VPN tunnel
I hope this will help
