Iptables missing flag --key on Debian 11

[rareshornet]

Hey thanks for building this! Nice easy way to deal with ISPs.

I'm not sure exactly what I'm doing wrong, using Debian 11(rpi pi) here, all compiled well and module loaded but I'm not sure why I get this flag missing error. Any ideas? Cheers.

sudo iptables -t mangle -I INPUT -p udp -m udp --sport 51820 -j WGOBFS --key mysecretkey --unobfs iptables v1.8.7 (nf_tables): unknown option "--key"

lsmod | grep WGOB xt_WGOBFS 16384 0 x_tables 53248 8 xt_conntrack,nft_compat,xt_tcpudp,xt_addrtype,xt_WGOBFS,xt_nat,ip_tables,xt_MASQUERADE
