How to redirect ports using Iptables
(It may not work depending on more iptables rules or firewalls)
Make the actual redirection from port 80 to 8080
iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8080
For debugging purposes or for loopback access of this rule, you need to enable loopback redirection too from your machine.
# syntax iptables -t nat -A PREROUTING -d [IN_IP] -p tcp --dport 3456 -j DNAT --to-destination 2.2.2.2:1234 iptables -t nat -A OUTPUT -d [IN_IP] -p tcp --dport [PORT] -j DNAT --to-destination [TO_IP]:[TOPORT] # example: iptables -t nat -A OUTPUT -d 127.0.0.1 -p tcp --dport 80 -j DNAT --to-destination 127.0.0.1:8080
