GUFW/UFW firewall troubles

English Applications
#1

Hi folks, not new to Linux but rather new to opensuse. I’m using opensuse 13.1.

I can not get gufw to load on start up with my few rules I use on other Linux OS.

I only have a few rules which are to Deny all in and out.

Then I load my rules as follow.

To Action From

80/tcp ALLOW OUT Anywhere
443/tcp ALLOW OUT Anywhere
25/tcp ALLOW OUT Anywhere
110/tcp ALLOW OUT Anywhere
143/tcp ALLOW OUT Anywhere
67/udp ALLOW OUT Anywhere
68/udp ALLOW OUT Anywhere
123/udp ALLOW OUT Anywhere
53 ALLOW OUT Anywhere
631 ALLOW OUT Anywhere
515 ALLOW OUT Anywhere
1194 ALLOW OUT Anywhere

My post at GUFW.

I went to the GUFW site and posted a question and it seems I am not getting to far with it, hoping someone who used or tried gufw can view the post and maybe give me a few suggestions. Many Thanks for your time.

Hi sammiev,

You do know that openSUSE has got a built-in firewall, do you?
You can set up the firewall in YaST (or switch it off if you want to use a different firewall).
I can’t help you with GUFW but I don’t think you actually need it.

Best regards

Hi Kasi, I thank you for your reply. I see from my link above that GUFW is still looking into my problem.
I took a shine to opensuse lately and moved it to my main OS as I test usually per released OS.
Yast is very new to me but what I like about GUFW is that I can export my rules and load them into most other OS.
Usually I have most OS fully running with all my applications wanted with 10 to 15 min after loading the new OS.
I may just have to learn the yast firewall after all.
Thanks

I see all your rules are egression rules. The SuSEfirewall2 allows you
“out” on all ports, and “in” on none, till you open them.

Found this on another site posted by handy and it works.

Required & important Terminal commands follow:

After installing (g)ufw, you must run the following command. **You won’t need to do it twice: **

Code: [Select]
sudo ufw enable
The next Terminal command enables ufw (on our systemd machines):

Code: [Select]
systemctl enable ufw

This command starts ufw:

Code: [Select]
systemctl start ufw
Run the following command at any time to view your IPTable rules:

Code: [Select]
ufw status
For more information on ufw enter the following command into the Terminal:

Code: [Select]
man ufw
