Title: How to block access between different subnet
Hi All,

I am using EG2100-P V2, setup 2 sub-interface with different subnets, I would like to know deploy the policy that the subnets cannot communicate each other, and only how to access internet.

How can I deploy the settings?

Thanks

Dear sir，

You can use the ACL to do it.

Please refer to this guide RG-EG Series Gateway Web-Based Configuration Guide

Source IP is the clients 1 IP
Destination IP is the other client 2 IP which you don't want client 1 to access

Created a new rule as attached, but still can ping the client address.

Is anything wrong?

I have applied the ACL to the sub interface say 2.1.

However, the machines not only cannot go to the destination subnet, but also cannot access internet (the gateway is 10.90.190.1 from my attached screen.

How can I solve the problem? Thanks
