Web accessible only when web cache is enabled

Hello,
I have just started to use a CCR-1036 and i decided to start of with a simple config and build up from there.
My config is as follows.
eth1 is connected to bridge one.
bridge one is a DHCP client and gets an ip address of 192.168.15.82

eth8 is connected to bridge8 and it runs a DHCP server
I am NOT using NAT and I am not using any firewall.
I have the following static route setup on my internet gateway so i can receive incoming/returning traffic.
dest = 192.168.108.0/24 gateway = 192.168.15.82

when i plug a pc into eth8 and get an ipaddress, i can successfully ping www.google.com.au from the pc command line
BUT if i go into my pc's browser, I am unable to connect to the website.
While investigating this, I turned on the web proxy and sent my browser through it...and it all worked and i could open the webpage.

Could someone please look at my config below and tell me what i may be missing to have web access without the web proxy enabled?

Thanks for your help
Stuart
