Can I use ufw to setup a port forward?

Question

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)

To have a concrete example, let's say you want to forward requests going to 80 to a server listening on port 8080.

Note that you will need to make sure port 8080 is allowed, otherwise ufw will block the requests that are redirected to 8080.

sudo ufw allow 8080/tcp

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.
