Redirect port 80 to 8080 and make it work on local machine

  • 772

I redirected traffic for port 80 to 8080 on my machine with

sudo iptables -A PREROUTING -t nat -p tcp --dport 80 -j REDIRECT --to-ports 8080

It works fine for all the world except my own machine. I am a developer and I need to redirect port 80 to 8080 for myself.

My IP is 192.168.0.111

My web server runs on port 8080

I wish to open website from http://192.168.0.111/ instead of http://192.168.0.111:8080/ from same machine where server runs.

iptables

    You need to use the OUTPUT chain as the packets meant for the loopback interface do not pass via the PREROUTING chain. The following should work; run as root:

    iptables -t nat -A OUTPUT -o lo -p tcp --dport 80 -j REDIRECT --to-port 8080

  2. Simple just use iptables allowing both port 80 and 8080 then redirect 80 to 8080 make sure you are assigning to the correct nic.. in example I use eth0 

    iptables -A INPUT -i eth0 -p tcp --dport 80 -j ACCEPT
iptables -A INPUT -i eth0 -p tcp --dport 8080 -j ACCEPT
iptables -A PREROUTING -t nat -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 8080

  4. Instead of the iptables, You could try: sudo ssh -gL 80:127.0.0.1:8080 localhost
