I have a virtual network setup with a Linux router/firewall connected to two private networks. An OpenVPN server in routing mode and a web server are in one of the networks. On the other are linux client machines which access the webserver and the Internet through the OpenVPN server. Also, external clients can access the OpenVPN from the Internet. The OpenVPN's server.conf is setup to use routing mode in udp, push DNS and routes to the network it is in so clients can access the webserver.

Here are my very strict firewall rules.

After connecting to the OpenVPN server, my clients can not access the Internet or the web server. When I allow FORWARD traffic to go through, it works just fine. The OpenVPN server has full internet connectivity. What firewall rule do I need to add to allow internet traffic to reach my clients?
