There was a message during boot which was not showing in dmesg and I finally captured a video of it. There were 2 warnings:

Problem running /etc/ufw/before.rules
Problem running /etc/ufw/after.rules

Both of those files existed and there was nothing abnormal about them that stood out. Found someone else who had the same messages.

Their solution included setting IPV6=no in /etc/default/ufw. After completing that step, the errors disappeared at boot and the work around is not needed.

This seems to be a work around for now.

sudo ufw disable
(count to 10)
sudo iptables -X
sudo ufw enable

Not really a fix and I have no idea why it has to be done at all. Trying to run the 2nd command immediately will cause it to fail because the firewall takes time to come down. No idea how to batch this to make it automatic, either.

So in reading this page https://askubuntu.com/questions/541675/ … s-to-allow there is mention to run iptables -X and restarting ufw. It seems that if you disable ufw, run iptables -X, and then restart it, traffic flows. However, it breaks again when you reboot. Seems like something is populating iptables and breaks the ufw firewall.

i don't use sylpheed but do use gufw and am interested in your mediation and conclusion(s)

i have briefly reviewed these but nothing jumped right out:

i use the gufw default home profile which denies all incoming and allows all outgoing
(sometimes make a temporary rule to allow seeding but that is quite infrequent)

[SOLVED] Assistance with Gufw

I am trying to set up Gufw to help protect my system, but am having problems with configuring it. For example, I am trying to configure rules for Sylpheed and Jami. Starting with just Sylpheed; the ports listed in my mail config are 465 and 993. Adding 465/993 to the allowed bucket still locks up Sylpheed when it tries to reach the mail box. These two commands were run:

sudo ufw allow imaps
sudo ufw allow submissions

The above targets are from /etc/services/. The connection is using SSL for IMAP and SMTP, but it will not connect through Sylpheed when the ufw is enabled. Not sure what I am doing wrong.
