pfSense

Renaming an interface to, in my case, RD_LOM_DISTRIBUTION caused this error:

Sep 17 18:43:39 f1 php: rc.bootup: New alert found: There were error(s) loading the rules: /tmp/rules.debug:177: rule label too long (max 63 chars) - The line in question reads [177]: block in log quick on $RD_LOM_DISTRIBUTION from 192.168.0.0/16 to any label "Block private networks from RD_LOM_DISTRIBUTION block 192.168/16"

I didn't test to see if the problem went away with RD_LOM_DISTRIBUTIO or RD_LOM_DISTRIBUTI but based on the error message, one of those should work. I always make fencepost errors when adding up things like this.

I'm unsure if the appropriate action is to limit the length of an interface name, or to truncate the pf labels at 63 chars when generating /tmp/rules.debug.
