I set up a very basic OpenVPN install, on an ASUS RT-N66U running Tomato Firmware 1.28.0000 MIPSR2-115 K26 USB VPN-64K. I generated all of the keys on my laptop, set up the time, etc, and everything seems to work fine. I set up client keys on my laptop, and laptop connects right to it. So far, so good.
My laptop has a tun ip of 10.8.0.6. The internal subnet is 192.168.1.1 inside the VPN. I try to ping a known ip inside the network, and no response. Then try 192.168.1.1, and still nothing. Then try 10.8.0.1, and still nothing. After a little bit, the VPN disconnects from activity. I have the firewall set to auto, is there some special iptables rules I need to put in to get it to route traffic?
