A (Non) Profitable Journey–Part 2 C

August 24, 2015

In my last couple of posts I described the fun I was having with trying to set up a coupe of open source firewalls to work in a fashion similar to what I normally do for my “paying” customers.  The results were less than stellar, I’m afraid, and I ended up pulling the firewalls.  But, Read More

Bear and Fish, Mark II

April 30, 2014

I made an earlier post about Sonicwall wireless issues here, this is a bit of a follow up to that post (or follow on). All Sonicwall firewalls come with a number of predefined security Zones that get applied to individual network interfaces on the box.  Some of the standard zones are Trusted, Public and Wireless.  Read More

Some days you are the bear and others you are the fish …

April 10, 2014

Today, I’m the fish.  Let me explain … I’m a fan of Sonicwall firewalls, that’s pretty plain to see if you have read much of this blog.  And I have been something of a fan of their wireless extensions, the SonicPoint’s and the SonicPoint management built into the firewalls.  What really got me going on Read More

Sonicwall DHCP server – static reservations

March 17, 2014

This is just a quick post to highlight a quirk I found with the Sonicwall DHCP server (built-in DHCP server in Sonicwall firewalls). I had an issue at a customer this past weekend where we had Cisco Access Points sitting behind a Cisco wireless controller and Cisco switch that pull their IP address from a Read More

Sonicwall Site-to-Site VPN Tunnel Counts–Something to keep in mind when you are sizing the firewall

January 23, 2014

Sonicwall firewalls are all capable of supporting site-to-site VPN connections to other firewalls and each firewall model has a specified maximum number of tunnels that it can support.  From 5 tunnels on a TZ105 through to 10,000 on the SuperMassive Series (ooooo, I want one of these for Christmas!!!!), they all work in the same Read More

Sonicwall firmware and the “one touch security config” (5.9.x), caution!

December 25, 2013

I recently installed a brand new TZ215W at a new customer.  I loaded the latest 5.9.x firmware (which I have used on other Sonicwall’s) and didn’t see any issues.  But I did try something new and that is the “one touch” security config button that you see on the Settings page.  I’ve never used it Read More

Sonicwall site-to-site VPN — the “easy” way

October 19, 2013

Site-to-site VPN connections are very easy to create between Sonicwall devices, almost ridiculously easy.  Here’s how to do it. Sonicwall let’s you set up site-to-site VPN’s in a number of ways.  I find the easiest and fastest way is to use the procedure that Sonicwall recommends when one of the VPN gateway Sonicwalls receives its Read More

Sonicwall “Zones” and “Portshield Groups”

October 18, 2013

I was running a Sonicwall lunch and learn with Jeremy and Louis yesterday and it became pretty clear that there was a lot of confusion about zones and Portshield groups.  I figured if they were confused there is a pretty good chance that a lot of other people would be, as well.  So, here is Read More

Migrating from one Sonicwall to another

October 15, 2013

Sonicwall likes to point out that their O/S – SonicOS – runs on all of their gear from the lowly (but good!) TZ105 to the mighty SuperMassive series.  While that may be true is does not immediately follow that settings from one Sonicwall can just be “dropped” on to another.  In fact, in many cases, Read More

A bunch of Sonicwall goodies–Part 3, Analyzer

July 31, 2013

If you manage a firewall — specially a UTM firewall that does all manner of things including tracking “content” and “applications – then chances are you are going to be asked by Management to provide reports and information about the “how’s” and “who’s” of bandwidth use.  It’s a fact of modern corporate life irrespective of Read More
