Rules for routing question

[James Knutson]

MY setup is an arris sb8200 modem to edgerouter lite(192.168.1.1) with eth1(192.168.1.0/24) to edgeswitch 24port managed and eth2(192.168.2.0/24) to ac68u b1(192.168.3.0/24), and off the ac68u I have a Cisco SG300(192.168.3.2) managed switch. The ac68u has merlin fw and PIA VPN setup. So everything through my edgeswitch is normal isp/home network and everything connected to my Cisco SG300/AC68u(Including wifi) goes through my VPN. Issue with my original setup was I wanted my Main PC(192.168.3.20) connected to my cisco SG300/ac68u used for programing and controlling/editing my smarthome system to send all internet through VPN tunnel but still have full access to my home network(192.168.1.0/24). I kind of guessed at the rules and just want to make sure they are right.
I have Policy Rules (strick) set and block routed clients if tunnel goes down set to yes
the rules i added
BlockWan 192.168.3.0/24 0.0.0.0 VPN
HomeNetwork 192.168.3.0/24 192.168.1.0/24 WAN

It seems to work perfect as I can access all my devices on my 192.168.1.0/24 network and when I go online my DNS and IP are from PIA. Done lots of testing. If my VPN connection Goes down will I still have access to my home network? Is this the right way to set this up?

Thanks in advanced for any help!
