@cheapsheep @eburom @magnavoid @OpenSourcerer Thank you very much for the bug report, the issue will be investigated very soon. In the meantime please force nftables (if available, and remember that userspace utility nft is currently required) as @cheapsheep suggested to circumvent the problem. EDIT: Eddie, Hummingbird and Bluetit assume that iptable_* modules exist if iptables exists. This is no more true in some distributions, where iptables userland utility exists but iptable modules don't
