Hello all, My linksys router is flashed with tomato usb firmware. It is configured for open VPN client. I asked my VPN provider for a script to break the uplink when the connection to the VPN server is lost. Otherwise, if the router loses connection to the VPN, it becomes visible with the IP address of my ISP. My VPN provider gave me this to put into the router firewall : iptables -I FORWARD -i br0 -o vlan2 -j DROP It does not work, when I stop the openVPN client, I am still connected to the internet through my box. I do not know the linux commands at all and I do not really know if this script does what I want… Could you explain to me and tell me if it does what I want ? Thanks !
