Can &nbsp;you show a screenshot of the firewall rule? Is it a specific port you are passing through?

Hi Team,<br />
<br />
I'm trying to add a rule to my personal sonic wall to allow access one of my devices from the outside. I have added the correct NAT and firewall rule but I keep on getting this error message on the logs:<br />
<br />
07/01/2012 12:58:31.272 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Notice &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Network Access &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TCP connection dropped &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;204.13.3.101, 40228, X1 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;192.168.10.20, 9090, X0 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TCP SonicWALL WAN Management &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4 (WAN-&gt;LAN)<br />
<br />
I even removed Rule 4 which blocks any wan to lan and I still get this:<br />
07/01/2012 12:52:01.768 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Notice &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Network Access &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TCP connection dropped &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;204.13.3.101, 40107, X1 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;192.168.10.20, 9090, X0 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TCP SonicWALL WAN Management<br />
<br />
<br />
Any ideas?<br />
Thank you

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.

Hardware Firewalls

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.
