[SOLVED] Which ufw file do I need to edit to correctly set up the firewall ?

[Member mikey777]

I subscribed for a ‘faster fibre’ broadband package, 35-37Mbps with TalkTalk, and received a new router from them today.
I was really shocked to discover that the router doesn’t have a preinstalled firewall (confirmed by TalkTalk), even a simple one,
as an initial defence for our home network.

Therefore, I assumed a firewall needs to be setup on my antixcore install. I downloaded ‘ufw’ and enabled it to start
automatically on reboot, which it does, but when it’s enabled it blocks my browser from opening. So, clearly I need to
reconfigure ‘ufw’.

Which ‘ufw’ file do I need to edit – is it just the ufw.conf file or are there others ?

Many thanks in advance for any help with this – much appreciated as ever.

There is an issue with the default 4.9 kernel on antix19 with ufw.
Is this your problem here?

@caprea
Your reply prompted me to test this with antiX kernels, other than 4.9
I found that the web browser (Falkon) was blocked with kernels 4.4, 4.9, 4.14 & 4.20.
The browser worked smoothly with either kernel 4.19 or 5.2.
All kernels tested were the ‘486-smp’ versions; I will probably test the ‘686-smp’ versions too, and post the result here.

You were spot on caprea, it was a kernel problem with my setup.
Many thanks for your help – much appreciated 🙂
