Problem with internet not stopping (using two routers)

[Guest rbj]

I have two routers connected together. One is connected to the local ISP and is for those family members who can't handle VPN. The other router is running DD-WRT w/AirVPN. The signal from the DD-WRT router goes through the local router.

In my VPN router I have this command: iptables -I FORWARD -s 192.168.1.0/24 -j ACCEPT. I assume this allows info to travel between the two routers.

I've tried to enter this in the DD-WRT:

iptables -I FORWARD -i br0 -o tun0 -j ACCEPT

iptables -I FORWARD -i tun0 -o br0 -j ACCEPT

iptables -I FORWARD -i br0 -o vlan2 -j DROP

iptables -I INPUT -i tun0 -j REJECT

iptables -t nat -A POSTROUTING -o tun0 -j MASQUERADE

These commands kill the command that links the two routers. Yet I still have VPN on the DD-WRT router. Should I be worried about this.

Thanks much.
