How do I configure a Sonicwall TZ210 to use a new CIDR block
Posted on 2011-09-15
I currently have a sonicwall tz210 - SonicOS Enhanced 188.8.131.52-52o , and have 8 static IP's assigned to us by Cox. I have been nating to 6 inside hosts, mostly rdp, and one web server. Everything worked fine untill Hurricane Irene. Cox is now having issues with nating in our area. They may not be able to fix it for a couple of weeks.
They suggested going to a CIDR block a /27. Does anyone know if my sonicwall can handle this type of addressing, and if so the steps to configure it to duplicate my current functionality. I'm not seeing anything in the documentation.
We work with the NFL, so busy season just turned on big time. Definitely not the time to be making big changes. Any help is GREATLY appreciated!
