Title: Zerotier, CARP clusters & multisite
Post by: random1104 on March 09, 2023, 01:10:46 AM
Hello!

How are you doing?. I have an scenario and I wonder what's the most straightforward solution.

Having several sites to connect, I'm thinking about deploying OPNsense in a small box on remote site and a two node cluster at the main office with zerotier connecting everything.

Now regarding routing:

- should I use no routing on zerotier + BGP in OPNsense, or should I use the embedded routing of zerotier?
- static routing setup on ZT is centralized and simple, but won't cover CARP scenarios with a gateway failover.

Regarding filtering:
- should I allow everything between gateways and filter everything in OPNsense?
- should I allow everything in OPNsense and filter everything in Zerotier?
- so a mix?, Filtering different things in both?

Hello!,

I've been looking for alternatives and would also like to hear from other SDWAN solutions that would play nice with OPNsense:

Tailscale/Headscale
Nebula
Netbird
Netmaker
