How Safe is WireGuard?

Configuration
1

I just installed the WreGuard add-on and I’m really digging the ability to access my LAN from the internet. I have a router from my ISP with the port forwarded to its only client: my UDM Pro, which manages my LAN …where I’ve forwarded the port again to my HA IP.

“IP Passthrough” is an option on my ISP’s router but I wonder whether I’m benefiting from using the ISP router’s firewall and yet another on my UDM Pro. I hope so.

I’m new to VPNs. Assuming my level of security on my LAN was 95 out of 100 before I installed WireGuard, what would my level of security be after setting up WireGuard?

“Chaining” firewalls do not increase the security per se, unless you are unsure of your UDM pro configuration.

All depends on what be the “clients” of your Wireguard VPN, really. The VPN itself is secured, and only designated device will be able to reach your LAN. Now, if the client device itself is compromised…
