Firewall Fast question

Hello everyone, i’ve just configured a RB751G to connect in PPPoE on eth1 to an ADSL modem configured in Bridge mode and it works flawlessly.
I want to know if i’ve understood correctly how firewall on routeros works.
I want to block access from everywhere to my RB port 80 except from my office static address so i’ve setup my firewall on chain INPUT and interface IN on eth-1 to drop any and flag the NOT check to my office address.
In this mode the rules doesn’t work, so i’ve configured the interface IN and put the PPPoE client interface and in this way it works.
My question is: the INPUT chain is not intended to control ALL traffic incoming into router? If this is correct, why it doesn’t drop?
Maybe i’m wrong on thinking that eth1 is WAN port?

Thank you :slight_smile:

Your wan port is the pppoe interface.

So to control traffic from the outside you need input rules which are on the pppoe interface.
