Manual Fix

The same rules may be created manually by adding one on the affected interface tab (e.g. LAN), and a second rule on the Floating tab using the same interface (LAN again) to match the traffic in the out direction. The rule must be set for a protocol of TCP, under TCP flags check Any Flags, and use a State Type of Sloppy State. The options for TCP flags and State Type can be found in the Advanced Features of the rules, under the normal options.
