I know this is probably the waaaayyyyy wrong place to for spelling-related questions :D...but I can't seem to find a definitive answer anywhere else:

Is it firewall ruleset or rule set?

According to Google, there's over 100,000 entres for ruleset.

Dictionary.com doesn't recognize the word, nor does my Outlook dictionary.

I'd go with the Google result.


Lats...

I would go for ruleset, it's a relatively new term but it is a noun nonetheless and shouldn't be separated into two words. At most it should be hyphenated, but I'd rather it wasn't.

Following Lats' lead I googled the terms (which I should have done in the first place :)):

ruleset: 99,600 mentions

"rule set" and "rule-set" (Google can't distinguish between the two): 50,200 mentions

So, ruleset it is :). Thanks!!
