Why does jump/goto not help? It works just like in iptables.
It does not help because of the way firewall4 is including custom
nftables chains for now. You need to add a hook yourself.
Firewall4 has a table called fw4, there they also hook e.g. to the
priority filter. Basically, your custom chain needs to hook filter
priority - 1 to be executed and whatever you do, the fw4 hook will be
executed afterward. I wanted to "go" over it. As I understand the
current discussion, the plan is to hook "only once" and allow to jump to
the custom chains from there.
Please keep in mind, that I am not the author of firewall4. I just
wanted to ask if something like this is or will be possible in the
future. I did not find any information about it on the internet. Thanks
for your answer.
