Original GitHub issue: https://github.com/netbirdio/netbird/issues/5114

It seems like this has been covered in a few other issues and I'd agree that posture checks in OSS could be more complete/versatile.

I'm thinking there's a gap in the current peer network address posture check implementation?

What if my office and home users share a lan CIDR? I'd want Netbird to enforce policy at home but not at the office? Is there any good way to accomplish this with the current posture checks?

Some things that could work:

public IP check (offices generally have static WAN IPs)
DHCP option check
gateway mac check
script based check
