Routing openvpn client connection to network computers

[blu702]

Hello all,

My scenario is as follows, a Linux box acting as a router. I want it to connect to the VPN client and then all the client computers on the network sending all traffic through that tunnel. I have everything setup except the iptables part. The scenario is as follows

WAN=eth1 (dhcp)
LAN=br0(bridge of eth0 & wlan0) (172.168.1.1/24)
tun0=openvpn

Everything is functional, but i can only get traffic to go through the tunnel if i set everything to accept.

pi@eRPI4rt:~ $ sudo iptables -S
-P INPUT ACCEPT
-P FORWARD ACCEPT
-P OUTPUT ACCEPT

I have tried all kinds of configurations to lockdown the firewall but none have worked.

Could you guys please help me?

Thanks in advance.
