pfSense

After upgrading to the latest snapshot, the filter rules refuse to load due to an error:

----
There were error(s) loading the rules: /tmp/rules.debug:109: syntax errorpfctl: Syntax error in config file: pf rules not loaded - The line in question reads [109]: nat on gif0 inet from ...0/ to any -> () ...

The bad rule from line 109 of /tmp/rules.debug:

nat on gif0 inet from ...0/ to any -> ()

The issue went away after I edited filter.inc line 3169:

if($int)
$lines .= "nat on {$int} inet from {$ipnet} to any -> ({$carp_int}) \n";

changed to

if ($int!='gif0')

this isn't the "correct" patch, but should help locate the issue. I am using manual outbound NAT rules.
