URL Port alias causes error loading rules in 2.2.4
It seems I did not consider the url_port alias type when "fixing" https://redmine.pfsense.org/issues/4844
This pull request for RELENG_2_2 hopefully will fix it: https://github.com/pfsense/pfsense/pull/1792
Awaiting forum feedback to confirm.
When fix is confirmed I will also make a pull request to master.
