EG3230 ACL to Block inter-vlan routing
469 2 2022-4-9 00:01:51
I created the DHCP, Sub-Interfaces on Te0/0


Then created the ACLs, 100,101,102 for each Vlan to block each other


Then applied the Interface Access Control to  Te0/0



I am still able to ping between several of the Vlans. Is there something I am missing?

others config

Dear sir,

Sorry for the late replying.
After viewing your description and configuration, I found that you set the wrong wildcard-mask of ACL. The wildcard-mask should be 0.0.0.127 according to the submask 255.255.255.128, and 0.0.0.63 for 255.255.255.192 in the same way.

And It's recommended that using the inbound for the Extended ACL filter direction.

Best regards,
Patrick
