    Question iptables not recognizing "--dport" or "--to-port" option

    Hello, I've been attempting to redirect port 80 to port 8080 using iptables v1.8.3 to test an SSL strip MITM attack.
    I've entered the command: iptables -t nat -A PREROUTING -i wlan0 -p tcp --dport 80 -j REDIRECT --to-port 8080
    upon entering it gives me the error: unknown option "--dport" it also doesn't recognize the "--to-port" option. I'm running Kali on a Rasberry Pi 4B 4GB Does anyone know how I can resolve this? I haven't found anything useful on the web after three days of troubleshooting.

    There is a typo in your rule preventing it from working: --to-ports (notice the s at the end) instead of --to-port
    Fixing that and the rule work just fine.

    Don't forget to have forwarding enabled (just in case the tutorial doesn't mention it)
