 # Connecting from the office
-A typical scenario administrators have is accessing their office networks remotely.

Still, administrators often want to avoid routing their users’ traffic via NetBird when they are in the office.
+A typical scenario administrators have is accessing their office networks remotely. With [Network routes](https://docs.netbird.io/manage/network-routes), NetBird makes this easy. Still, administrators often want to avoid routing their users’ traffic via NetBird when they are in the office.
 To solve this, administrators can leverage the power of [Posture Checks](https://docs.netbird.io/manage/access-control/posture-checks) and create policies that allow connection to the routing peers only if they are outside the office by using
 a [Peer Network Range](/manage/access-control/posture-checks#peer-network-range) posture check with a block action.

+Now, let's create a [Network Route](https://docs.netbird.io/manage/network-routes) that will expose the local office subnet `192.168.1.0/24`,
 which will be distributed to all peers members of the group `route-users`. In this example, we will be using a routing peer named `router-01`,
 which is a member of the group `route-nodes`, this way, the policy we just created goes into effect, and all peers from the group `route-users` will be able to reach
 `router-01` only if they are not in the office network, due to our posture check.
