VLAN Security

Hi again,

The ACLs you are looking for are called extended ACLs. They are numbered 100-199 and can be created by going to: "Security" --> "ACL" --> "Advanced" --> "IP ACL" --> In the "IP ACL ID" type 100 and click "Add".

This will create rule table 100. Now, you can add rules to the table as you wish. Go to "IP Extended Rules" and you can see your table here. You can start adding rules.

Once you have the rules you need, then you can bind the rules to ports via the menu "IP Binding Table".

A few notes about ACLs.
1. They use wildcard masks instead of subnet masks.
2. ACLs are read from top --> bottom. This means specific rules on top, general rules at the bottom.
3. Remember that the default (hidden) rule on an ACL is "Deny All". What you want is block some stuff and allow the rest. This means that your last rule should be Permit All.
4. The ACL direction is Inbound on these switches. That matters for how you create the ACL :)
5. Only bind the ACL on the relevant ports. If you bind it to all ports and you make a mistake, you might block access to the switch itself, which you in turn can't recover from (as the ACL is applied on all ports and there is no console port on these models).

Here is a Netgear KB about it: https://kb.netgear.com/21714/How-do-I-set-up-an-IP-Access-Control-List-ACL-with-two-rules-using-the-web-interface-on-my-managed-switch

Cheers!
