Description

There were error(s) loading the rules: /tmp/rules.debug:186: rule expands to no valid combination - The line in question reads [186]: pass in quick on $LAN inet6 proto tcp from any to 192.168.100.1 port 2022 tracker 1428944337 flags S/SA keep state label "USER_RULE: NAT redirect regular SSH port to 2022 on LAN"

Caused by an error in the rule, I had an IPv4 destination on an IPv6 rule.
I would suggest additional input validation on the rule entry page to prevent this, because I didn't realize what the problem really was until I was halfway through filing a completely different bug report that would have made me look... well, oblivious, at least.
