Question
- Port forwarding#advancedFirewalls can not only filter requests, they can also forward them.Requirements:Configure web-01 so that its firewall redirects port 8080/TCP to port 80/TCP.Your answer file should be a copy of the ufw configuration file that you modified to make this happen
Solution
To configure port forwarding on web-01, follow these steps:
-
Open the ufw configuration file. This file is typically located at
/etc/ufw/before.rules. -
Locate the section where the firewall rules are defined. This section is usually marked with the comment
# START OPENVPN RULES. -
Add a new rule to forward port 8080/TCP to port 80/TCP. The syntax for the rule is as follows:
-A PREROUTING -p tcp --dport 8080 -j REDIRECT --to-port 80 -
Save the changes to the ufw configuration file.
-
Restart the ufw service to apply the new configuration:
sudo service ufw restart
After completing these steps, the firewall on web-01 will redirect incoming requests on port 8080/TCP to port 80/TCP.
