I have a Sonicwall Pro 2040 and I'm having the strangest issue. From our company site we cannot access websites, receive mail, or do any other external forms of traffic. However, I can easily connect to my server using the Sonicwall VPN from off site. If I remote desktop to a computer while doing the VPN I cannot access the internet (from that remote desktop) yet I can easily do all of it on mine (the one I'm connecting from).
Any ideas on what I should look at or anything else that might help describe the issue more? I've checked everything from the router to the access rules. What really threw me was that I can easily connect to our network from home. And yes, our internal networking is working fine.
