I have two x1000 fireboxes, one at my office and one at a client. The one at my office I have the optional interface configured to allow guests to get out to the internet, works fine. I have the one at the client configured the same way, but it will not allow the client to get to the internet. I can the ping the gateway of the otional interface and it will show up in the traffic log, but no other traffic will show up. The firmware levels are the same (7.5), the system manager software (10.2) being used is the same. I have even tried to create a minimum config for the second x1000, wrote it out to the device, but it still did not allow traffic out to the internet. Does anyone have any idea as to what I may be overlooking?
