UFW firewall

[yuma]

This is not a problem.

Just wanted to let you know I use UFW on Ubuntu as my firewall. The install script was not able to automatically disable it - no problem, I did it manually. (If not known the command was ‘sudo ufw disable’.)

@yuma Which version of FOG and Ubuntu do you use?

We use exactly the same command to disable the Ubuntu firewall (code ref). So it’s interesting to here this did not work in your case.

Forgot to mention I used the latest install script, I believe, fog 1.5.9. On the latest Ubuntu 20.04.1.

@yuma Ok, turns out that even though we use ufw disable it does not properly remove all the chains and rules it creates. This seems to be a known issue.

While we surely can add this block of iptables calles to clean it up I am wondering if we should actually do this as it’s really ufw’s job to do.

iptables -P INPUT ACCEPT
iptables -P FORWARD ACCEPT
iptables -P OUTPUT ACCEPT
iptables -t nat -F
iptables -t mangle -F
iptables -F
iptables -X
