How to install iptables extensions? I get "Extension owner revision 0 not supported"

[anon4]

I'm trying to do

Code:

sudo iptables --append OUTPUT --match owner --gid-owner allow-net --jump ACCEPT

which works on my desktop but when I try to do it on the pinephone I get

Code:

Warning: Extension owner revision 0 not supported, missing kernel modules?
iptables: No chain/target/match by that name.

The owner iptables extension seems to be installed though because I can do

Code:

sudo iptables --match owner -h

and I get the man page for owner
