Hi guys! Has anyone here tried blocking an IP on the same subnet? Then, only selected ones are allowed to access a specific IP?

HiHi,

Please try to add the IP address to the Global Blacklist.
See the below information for your reference:
In NGAF Platform\SOC\Blacklist\Global Blacklist.

Hi, you can use Newbie517762 method of black list or configure in the access control policy. For me a blacklist is kinda an overkill hahaha. never thought of that way before

Clients do not even go through the firewall when they are accessing others in the same subnet.

Create an access control list (ACL) to define the desired traffic policies. First, identify the IP addresses to be blocked and allowed within the subnet. Then, configure the ACL to deny traffic from the blocked IPs while permitting traffic from the selected ones to reach the specific IP. Ensure proper subnet masking and specificity in the ACL rules to accurately target the desired IP ranges.

can be achieved by using ACL.

You need to create policies thru Access control List or ACL to allow/deny access to certain IP address on the same subnet

Hi, you can try to establish an Access Control List (ACL) to outline the required traffic rules. Initially, pinpoint the IP addresses that should be permitted and blocked within the subnet. Next, set up the ACL to reject traffic from the blocked IPs while allowing traffic from the chosen ones to access the specific IP. Make sure to apply correct subnet masking and precision in the ACL rules to precisely target the intended IP ranges.

Hi,

You can use Access Control Lists (ACLs) to block specific IP addresses. ACLs are a set of rules that control network traffic and can be configured to deny or permit traffic from certain IP addresses to enhance network security.
