Web Filter blocking Amazon

AaronOsmer
Yesterday my web filter started blocking Amazon. The only way I can seem to fix it is turning off the web filter. I tried creating an exception, but it still wont work. This behaves the same on PC and Mac, but it loads fine on my mobile devices. Any ideas?

    The nic idea got me thinking, so I switched my internal/external vnics with each other and like magic it's started working again. Still doesn't explain what was going on, but for now the issue seems to have ironed itself out.

    Thanks again for the help everyone!

    Speed / Duplex mismatch with your switch or the ISP CPE -- seen it before, random, random failures to browse (some sites work great, some don't) -- found it to be a speed/duplex mismatch at the physical layer.  Typically locking down speed/duplex settings on both pieces of equipment squares it away.  If you log into the console of the UTM (or in this case, host server), look for excessive CRC errors -- you can also look at your switch statistics if you are using a managed switch.
