Hi,
tried to create a rule using the conntrack state of a packet:
[root@sarkovy nftables]# cat ruleset-own.txt
create table netdev world
add set netdev world blacklist { type ipv4_addr; flags dynamic,timeout;
timeout 1h; gc-interval 6h; size 256; }
create chain netdev world ingress { type filter hook ingress device
"eth_cable" priority filter; policy drop; }
add rule netdev world ingress ip protocol tcp ip saddr @blacklist
counter drop
add rule netdev world ingress ct state established,related counter accept
[root@sarkovy nftables]# nft -cf ruleset-own.txt
ruleset-own.txt:5:31-38: Error: Could not process rule: Protocol error
add rule netdev world ingress ct state established,related counter accept
^^^^^^^^
This is rejected, but why?
And, btw., which one is correct, 'ct state established,related' or 'ct
state { established,related }'?
