Linux UFW firewall rules about localsend

[cyrilberrypi]

Hello @wizard1989

Here is what I found to assist you going forward.

To allow the "localsend" application through the UFW firewall, you'll need to allow the specific ports that "localsend" uses. If you're unsure which ports "localsend" utilizes, you can typically find this information in the documentation or configuration files of the application. Once you've identified the ports, you can create UFW rules accordingly.

Assuming "localsend" uses TCP and UDP protocols on port 12345, here's how you can create UFW rules for it:

1. Allow TCP traffic on port 12345:

   sudo ufw allow 12345/tcp
   

2. Allow UDP traffic on port 12345:

   sudo ufw allow 12345/udp
   

If "localsend" uses additional ports or protocols, you'll need to add rules for those as well following the same syntax.

After adding these rules, make sure to enable UFW to apply the changes:

sudo ufw enable

Here's how you would create a UFW rule file specifically for "localsend" application, assuming it uses TCP and UDP on port 12345:

# localsend UFW rule file
# Allow TCP traffic on port 12345
-A ufw-user-input -p tcp --dport 12345 -j ACCEPT

# Allow UDP traffic on port 12345
-A ufw-user-input -p udp --dport 12345 -j ACCEPT

Save this content to a file, for example, localsend.ufw, and then you can apply these rules using the ufw command:

sudo ufw --file localsend.ufw enable

This will enable the UFW rules specifically for the "localsend" application. Make sure to adjust the port numbers and protocols according to the requirements of your specific application.
