We increased our address scope from /23 to a /22. I have updated all of our switches and access points to work on the new scope. But when I add /22 to my local interface on my Firebox M500, the firewall will become unreachable. The only way to revive it is to reset to defaults and reload the config.
I contacted Watchguard about the issue and their response was that I should segment the network instead of making this change and closed my case. That actually kinda rubbed me the wrong way and I dont agree with their fix. This is in a school and having 1024 addresses doesnt seem to be a large scope, as we are only using a little over half. I would eventually like to segment the network, but we are in session here and will have to wait until next summer. I need the firewall to recognize all 1024 addresses right now...
