hello everyone

gre tunnel work on single core ?
because i using +150kpps on gre tunnel and my single core overloaded

when ddos is come from gre tunnel 70-80k pps gre tunnel cpu overloaded to %70

i using i9-9900k processor and vyos directly installed to this dedicated server

Try to enable rps

set interfaces ethernet eth0 offload rps

after gre tunnel can work on multi core ?

i tried this but it got worse

Could you try to add the following optimisation and compare results?

sudo su -l
echo "ff" > /sys/class/net/tun0/queues/rx-0/rps_cpus

Note: You need to disable HT

Also increase ring buffers. Bit more about system optimisation you can read by the following link System optimization - Knowledgebase / General / System Settings - VyOS

i need to reactive again this ?
“set interfaces ethernet eth0 offload rps”

i get same results my cpu overloaded

i tried offload rps and echo “ff” > /sys/class/net/tun0/queues/rx-0/rps_cpus its not successfuly

i will try disable hyperthreading

i get +600k pps attack from gre tunnel and my tunnel cpu overloaded network down

after disable hyperthreading on getting 850k pps attack from tunnel
results;

hello sir

my problem still next

i live same problem on gre tunnel, emergency!
