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.

Re: Assistance with Gufw

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)

Re: Assistance with Gufw

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.
