Fix extra quotes in firewall string matching
Fix extra quotes in firewall string matching

As reported by Steve Traylon[1] and @patricknelson[2], the munging adds extra quotes to the string.
This breaks the string matching in iptables, as it looks for literal single quotes in the match.

Removing the munging fixes this.
