Model : TL-ER6120

Hardware Version : V1

Firmware Version : 1.0.5 Build 20130314 Rel.56468


Hi there,

I use the ER6120 in a small business environment with 3 PCs, 1 Server and 1 NAS.

The Server is on LAN Port 1, the NAS on LAN Port 2 and a switch on LAN Port 3, where the PCs are connected.

I want to use a rule to block traffic to the NAS for all clients except for the server.

I entered a new Service called "All" for TCP/UDP Port 1-65535.

This is my configuration of the Access Rule:

Policy: Block
Service: All
Interface: LAN
Source: IP/MASK
Destination: IP/MASK
NAS IP /32
Effective Time: 0:00 - 24:00

xSun xMon xTue xWed xThu xFri xSat
Description: NAS Block
Priority: 1

I still can access the NAS from anywhere in my network! The Webpage is accessible and even the network shares are accessible.

What am I doing wrong?

Best regards

I think what is going on here is you are getting switch traffic and router traffic mixed up. The traffic you want to block is layer 2 traffic, switch level traffic. You are creating a layer 3 router level block. The layer 2 traffic is not required to pass through a router for access so the traffic is isolated to only the switch without being routed so it cannot be blocked at the router level layer 3. I hope this helps.
