UFW and iptables issue with port forwarding

Hi all

I am relatively new to UFW and iptables.

I need the following port forwarding to be permanent: 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 iptables -A INPUT -i eth0 -p tcp --dport 443 -j ACCEPT iptables -A INPUT -i eth0 -p tcp --dport 8443 -j ACCEPT iptables -A PREROUTING -t nat -i eth0 -p tcp --dport 443 -j REDIRECT --to-port 8443

I have enabled UFW and made settings in there as well.

When rebooting the UFW settings remain but the iptables settings disappear.

How do I make them permanent? Preferably via UFW - if possible.

UFW is a simple frontend for IPtables, and does not allow you to configure everything that IPtables does. Though it does make many common task easier. If you have more complex firewall rules you need to setup, you can use the files:


Placing IPtables rules in before.rules will apply those rules before starting UFW. Likewise, rules placed in after.rules will be applied after UFW has started in case the order matters.

There are also the files:


They behave similarly, except that you can execute any arbitrary script rather than just IPtables rules.
