Hi there,
With any VPN setup you will typically require an ACL which is used to identify "interesting" traffic (the encryption domain) destined for the remote end which will be sent via the VPN.
Looking at the RV320 configure guides it would appear that you can only define a single subnet in this ACL. The issue you have is the 192.168.2.0 subnet lies between 192.168.1.0 and 192.168.10.0 and 192.168.20.0.
Due to this limitation you need to ensure each site is allocated a contiguous address block (this would be good practice TBH) ,eg:
Office : 192.168.0.0/20 -> 192.168.0.0 - 192.168.15.254
Remote: 192.168.16.0/20 -> 192.168.16.0 - 192.168.31.254
Obviously this will require to re-subnet both sites.
Alternatively just configure static routes on the remote site RV320 with the next-hop address set as SVI IP for 192.168.1.0 subnet.
cheers,
Seb.
