No Comments
| Firefox, Sonicwall

Wow… This is a problem that you kind of, after looking at it, cannot point fault at, but realize it just takes a little common sense to fix it… let me explain…   When you create a new Sonicwall setup, Sonicwall by default sets the HTTPS certificate name to 192.168.168.168….

| Sonicwall, Windows 7

A while back, I was really happy with Sonicwall, and really excited when DELL bought them. I had high hopes for Sonicwall in that just maybe, JUST MAYBE, Sonicwall support would get much better.

Sonicwall port errors? What’s really going on with Ethernet Autonegotiate

No Comments
| Hardware, Sonicwall

While working on Sonicwall routers, I found some interesting things. After setting up monitoring of the Sonicwall routers via Cacti, I was able to turn on monitoring of “errors”. As I found errors on the ports, almost every error was due to the port on either the Sonicwall or the switch being set incorrectly.   […]
