nftables includes some interesting math operations generators which can be used to perform advanced operations like Load balancing.
Number generator
The number generator statement has these options:
- type: inc/random.
- modulus: maximun number
- offset: from what value you want to start from
Some examples, distributing marks to packets:
table ip t {
chain c {
mark set numgen inc mod 4 offset 3
mark set numgen random mod 50 offset 20
mark set numgen inc mod 100
}
}
