iptables-restore - what does `:CHAIN` do?
Multi tool use
This is a followup to https://unix.stackexchange.com/a/400203/21615 .
When using iptables-restore --noflush, :<chain> <policy> [<packets_count>:<bytes_count>] seems to flush the chain if <chain> is DOCKER-USER but does not flush if <chain> is INPUT.
Why is that?
Both chains exist when running iptables-restore. INPUT has a default policy, but DOCKER-USER does not. The last rule of DOCKER-USER is to RETURN to the FORWARD chain.
