Im currently using ufw to enforce some basic firewall rules. Is it possible to also use ufw to do port forwarding?

Specifically im wanting to forward incoming traffic to my server (same machine running ufw) on port 80 to port 8080. (http traffic forwarded to tomcat)

Add before filter section in /etc/ufw/before.rules(top of file):

*nat
:PREROUTING ACCEPT [0:0]
-A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8080
COMMIT

Then restart ufw.

could you explain this line by line please? also, is there not something like ufw forward 80 to 8080? I thought UFW was Uncomplicated. –  Tom Mar 11 '12 at 11:58
    
Looks like there are no ufw commands for setting up the port fowards, so it must be done via configuraton files. More detailed description about the configuration file syntax is available at: frozentux.net/iptables-tutorial/… –  Juha Palomäki Jul 24 '12 at 9:01
