    Here's the setup I've got...

    Cable Modem -- Router 1 (
    |Port 1 - Device
    |Port 2 - Device
    |Port 3 - Router 2 (

    So the second router is used to connect to a VPN service and access the internet. I do not want Router 2 to access the LAN on Router 1. I've tried many variations of iptables -A OUTPUT/INPUT drops, but can't succeed just yet. Any suggestions at ensuring Router 1 doesn't let Router 2 access any of the devices on it's lan.
