Gateway Virtual IP VPN setting question

I have an RV50X. I am configuring IPSec VPN Site to Site. I have done an million times sucessfully with LAN terminated. I see the host terminated option now. Is the Gateway virutal IP setting meant to provide SNAT to LAN?

For Ex, my RV50 LAN is
But lets say this subnet is used everywhere (other sites), and I want to SNAT to avoid changing a bunch of equipments LAN address while being able to VPN to all the sites).

So does setting termination to host and setting gateway virtual ip to basically set a SNAT from 10.2 to 13.X. I assume it does this by following port forwarding settings?

Please advise
