Iptables – Opensuse port forwarding 80 to 8080 not working

glassfishiptablesnetworkingopensuseport-forwarding

I've a glassfish server that use the port 8080.

I need forward from port 80 to 8080 so I can access the content without put the :8080 port in the url.

I've tried to put a masquerade rule, add iptables rules but nothing changes…

The last iptables rule that i've tried is:

sudo iptables -t nat -A OUTPUT -d localhost -p tcp --dport 80 -j REDIRECT --to-port 8080

That come from this post Port 80 redirect does not work for localhost the problem is that nothing changes.

The version of opensuse is: 13.2

What I miss?

Try below iptables rules, it should work for you

sudo iptables -I INPUT -p tcp --dport 80 -j ACCEPT
sudo iptables -I INPUT -p tcp --dport 8080 -j ACCEPT
sudo iptables -t nat -A PREROUTING -p tcp -m tcp --dport 80 -j REDIRECT --to-port 8080

Also SuSEfirewall2 regenerates the iptables on each boot. So if you want to save rules then you can add "custom rules" using the file: /etc/sysconfig/scripts/SuSEfirewall2-custom

Centos – iptables: forward port 80 to port 8080

You cannot specify the table like that in/etc/sysconfig/iptables. Each table is set with an asterisk then the table name. Here is a skeleton of what you'd do:

*nat
:PREROUTING ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
:POSTROUTING ACCEPT [0:0]
-A PREROUTING -i eth0 -p tcp --dport 80 -j DNAT --to-destination :8080
COMMIT
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
COMMIT

Instead of editing the file you could also manually set up the rules you like using the iptables command and then execute iptables-save > /etc/sysconfig/iptables or service iptables save.
