how to isolate the two subnets on TP-Link WR840N
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
I have a simple home LAN that consists of one router without WLAN.
I want to share internet connection with a second router so that devices that connect to the second router can't communicate with devices that are plugged in the first router.
I have connected a second router (TP-Link WR840N) by connecting UTP cable from my main router's LAN port to my second router WAN port. It is set to Router mode.
Main router's IP address is 192.168.8.1
Second router's IP addresss is 192.168.9.1 and I have configured gateway and DNS as 192.168.8.1 and DHCP as 192.168.9.100-192.168.9.199
I want to block communication between the two subnets, so that devices that connect to second router via WiFi can have internet connection but can't communicate with devices on the main LAN (192.168.8.X).
I tried by configuring Guest option, but I can still reach my main LAN through it.
*** EDIT - SOLUTION *** - IS THERE A BETTER ONE?
I managed to do it via Access Control
here are the steps:
1.
In Access control - Rule:
- enable internet access control
- allow the packets ...
SAVE
2.
In Access control -> Target:
- add new:
mode: IP Address
description: "mainLAN"
IP Address: 192.168.8.2-192.168.8.255 (note: 192.168.8.1 shouldn't be blocked because it's the internet gateway address)
SAVE
3.
In Access control - Rule:
- Add New
description: blockingmylan
Lan Host: Any Host
Target: mainLAN (Add target: mainLAN, previously configured)
Schedule: any time
Rule: deny
Status: Enabled
Direction: OUT
Protocol: ALL
You can try to restrict access to router 1 LAN by using the Access Control:
On router 2 enable Access Control with allow default filtering rule:
and Save.
Create a Target and Save:
On router 2 add a rule with these settings:
and add the previously created Target to this rule. Save and test if that works for you.
