Forinet support figured out my problem. It was one of my static routes
that was reconfigured. Had a rule 172.0.0.0 to my gateway, when it
should of been 172.16.0.0 Thanks George at Fortinet for spotting my
problem.
I am having the same exact problem. Websites like ebay.com or msn.com do
not load or if they load they do not load images. Rebooting my 300D
fixes the problem only for a short time.
