Help Please: openVPN iptables trouble

I followed the helpful community guide to setting up openVPN on my Linode but I am running into problems that relate to my iptables config.

I am a total amateur at server configurations so my pre-existing iptables entries are all from a previous guide I used to get my server up and running.

The situation is that I can connect via an openVPN client to my Linode, but I can't browse the web. For example, I can't browse to google.com and I can't ping google.com, but I CAN ping an IP Address.

If I flush iptables then everything works just fine.

Here is my iptables.up.rules file – the only additions I made during the openVPN install are the three lines under "# Allows openVPN connections"

Any help anyone could offer for getting me back on the right track will be very much appreciated!
