Kubuntu firewall blocking internet access after downloading UI

aw flag
Adam

We've tried setting up a plex server on two occasions, and both of these times we've run into trouble where the commands for allowing ports on the firewall does not work, so we end up downloading the firewall UI from discovery.

After just downloading the application, what happens is that we lose internet access, and we have to execute :

sudo ufw reload

everytime we start these computers.

It's really annoying and we're not sure what to look for, in the UI you can choose between block, dmz, drop, external, home, internal, nm-shared , public, trusted, work.

Each of these have different boxes ticked with DHCP and some with SSH, and i'm unsure if any of these could cause this issue.

We're using Kubuntu 21.04 , 5.21 KDE Plasma.

Pretty sure we're using different kernels on the machines too.

Any form of ideas or help would be greatly appreciated.

Edit:

These are the commands we've tried :

 sudo ufw enable

 sudo ufw status

 sudo ufw allow from 127.0.0.1:32400

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
