Question regarding nfqueue

Hello i have 2 machines i am trying to protect the one from behind i am in inline mode through a gre tunnel

Everything is perfect the attack is getting dropped but i have a error in dmesg

[ 3947.801242] nf_queue: full at 262136 entries, dropping packets(s)

I increased that max-pending to 65534 but that is the limit

Is there anyway i can increase that ?

I have enough ram and cpu free they didn’t use it not even 25% procent of it

The machine where suricata is it have dual cpu with 16c/32t
64 ram

Thanks!

Or maybe that is the max limit that i can use with nfqueue ?

As i can’t push it anymore i need to switch to af-packet mode ?
