Road warrior setup question

[zerapio]

Hello, I'm considering using Algo to access my home's private network; similar to the road warrior setup. As I understand, the road warrior setup has Algo running in the home network with ports opened on the home router. My planned setup is different. I have a Synology NAS and all of my gear behind a double NAT. Rather than open ports in both NATs I would have the NAS and all devices that need to access the local network connect to Algo. Here are my questions:

• From what I can tell Wireguard supports split tunnels but can it be configured to not tunnel LAN address when inside the nerwork? (I think this is like a loopback detection)
• If the home NAS has DHCP and DNS servers can clients outside the network get an IP and name from them? (I'd like to refer to devices in the network as printer.home.domain.com instead of an IP)
• Is there are simpler way to implement what I'm trying to do?
