I used to be a manager for a large book retailer. The system/browsers there were locked down/set up to only allow certain IPs and email addresses within the company, in and out. was annoying when I tried to use my company email from home to send info to my coworkers. I often would have to do some researching at home;I was denied EVERY time.
Their reasoning is that OUR resources are sufficient enough to get any information/item needed, so there no reason to go elsewhere. (NOT TRUE,BTW! Company lost many a customer to competitors with this attitude. )
I am pretty sure that they used a firewall, but when I asked, was evaded.
They also had a type of VNC so the offsite IT could enter into a store's system at will.


Not sure if this helps...
