ACL for Internet only

JustTakeTheFirstStep — Mon, 05 Jul 2021 20:23:53 GMT

I want to deny the internal network (172.16.0.0 ~ 172.32.0.0) and permit only the Internet.

Is there a problem with my ACL?

172.27.144.0 : Wireless

172.30.1.61 : DHCP

172.30.1.15 : DNS

172.25.1.201,208 : Fileserver

Thank you.

you need to streamline the ACL - what device is this RV?

First, you need to deny going to the internal network to internal network deny then allow the source of 172.X to destination internet allow.

then last is deny any.
