Wireguard VPN - Some devices not respond to ping

RouterOS Beginner Basics

Hi to all…
I’ve configured a wireguard tunnel on an HAP ac2, my lan have subnet 192.168.1.x (mikrotik on 192.168.1.1), the wireguard interface address is 192.168.3.1, the remote client have 192.168.3.2 address.
I’ve configured an src nat from 192.168.3.0/24 to address 192.168.1.0/24.
All seem to work, i ping several devices on the network and access them (can access also the mikro at 192.168.1.1), but some devices doesn’t respond (also an home assistant on a pi4 doesn’t respond).
I think (but maybe i’m wrong) that some devices not allow connections from ip’s outside the lan. I’ve tryied so to use for the wireguard interface a local free ip address 192.168.1.190, but this makes the mikro inaccessible.
Someone have some ideas?

Thanks!!

Serm to be fixed setting the to-addresses of the src nat with the ip of the router (192.168.1.1).
