Limit a particular client to only communicate with another client on LAN

Sun May 30, 2021 12:29 pm

Hi,
I just installed a CCTV NVR that needs to be connected to my local network to view its footages.

However, I do not want the NVR to be able to:
1. access the Internet
2. access any other part of the LAN except with the client that will be used to view footages

I am new to Mikrotik firewall and have no idea how to configure.

Any help is appreciated, preferably exact instruction because am a total noob in network security 😅

Thanks.

Filtering devices that are on the same LAN is tough because they are generally not going through the router. However if you create a separate VLAN for the NVR, it is easy in firewall rules to allow and disallow what can get to what.

Access to the Internet will be blocked using the Firewall (Layer 3 Traffic)...
As for the LAN (Layer 2 Traffic) filtering, either use Bridge Firewall or VLANs...
