Mishandling in-kernel ipTables

FWBuilder 5.1.0.3599 running on Mac OS X Sierra.
Used to manage a D-Link DIR-880L flashed with DD-WRT v3.0-r27858
DD-WRT compiled iptables v1.3.7 straight in the kernel instead of using it as a module loaded by the kernel
When installing the rules on the router, FWBuilder complains that the modules was not found and report an error. Despite the Failure message returned, the rules have been deployed properly.
FWBuilder also complains that br0 interface does not exist when asked to check the interfaces during deployment. Well... It does exists and rules re-using that interfaces are properly injected and enforced.
Congrats on your great interface for FW management,
