No known issues. What I'd recommend is getting a backup of the current firmware WITH the current settings. If things go awry, boot the sonicwall into safe mode and load your backed up firmware with settings. The article below is how to use safe mode.<br />

Awesome, that's what I'm doing, too. Mine is definitely as 2400 though... older model (3 years old) than 240 I think.

Amazing! We answered this question at EXACTLY the same time!

<div>
No doubt... <br />

The 240 is just a smaller not quite as powerful 2400 I have a brand new 240 and an older 240, biggest difference is the 2400 is rack mountable where the 240 is not.

Are there any known issues when upgrading from 5.2.0.1 to 5.6.0.10? And can I just import my backed up settings to get ALL of my settings back after the upgrade? Or does it keep all settings as long as the firmware upgrade is clean?

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

Software firewalls, also known as host-based firewalls, provide a layer of software on one host that controls network traffic in and out of that single machine. Most operating systems now include firewall software, but many available software firewalls include central distribution, antivirus systems and disaster recovery.

Software Firewalls

Networking hardware includes the physical devices facilitating the use of a computer network. Typically, networking hardware includes gateways, routers, network bridges, modems, wireless access points, networking cables, line drivers, switches, hubs, and repeaters. But it also includes hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, ISDN terminal adapters and other related hardware.
