# SCAMMER WARNING

### IPTABLES for nfqws

> [!CAUTION]

> Starting from Linux kernel 6.17 there's CONFIG_NETFILTER_XTABLES_LEGACY parameter which is not set by default. Many distributions will likely will not turn it on making iptables-legacy non working. This is part of iptables deprecation. However iptables-nft still works because their backend is based on nftables.

This is the common way to redirect some traffic to nfqws :

```

# zapret v71.3

# zapret v71.4
