I can access their site and I can see all the different size files to download. When I click on any of them it takes awhile to load the "Oops! Google Chrome could not connect to download.thinkbroadband.com" page. I haven't had a chance to throw my old router up and check if I can get to that site to download those test files.
Yes I did remove my WAN IP information on purpose. I have a standard Cable internet connection from Cox Communications and my IP address is DHCP assigned. I'm currently using a Motorola DOCIS 3.0 Modem. I haven't had any internet issues before installing the pfSense box.
I have the MTU size on the WAN interface set to use the default size.
BTW thank you for your help!!
