Original GitHub issue: https://github.com/netbirdio/netbird/issues/1146

Currently, it seems like ACLs in Netbird allow us to specify only groups.

In my scenario, I have a peer acting as a relay, exposing multiple network routes on a remote network. I'd like to restrict access for a specific group (e.g., "devs") to only a subset of this remote network (e.g., only to the DEV subnets) by specifying network ranges/CIDRs.

I also hope to add this feature, which will completely crush headscale

Hello, we are closing this as a stale issue for consolidation. Granular access to subsets of a routed network is supported through Networks resources (IP ranges/CIDR in resource groups + policies) and on Network Routes by assigning ACL groups per route and splitting subnets into separate routes. Policies still use groups as sources/destinations rather than inline CIDR fields. If you need CIDR directly in policy rules, please open a GitHub Discussion with your topology (Networks vs Network Routes, masquerade on/off). Thanks!
