Stopped working recently?

Recently the script stopped working, i tried it with 3 different servers. Usually everything was blocked correctly. But now it does not seem to block anything anymore. I verified the ufw rules and i verified that the firewall configuration was there, still no success (ubuntu). Did anything change in a recent docker release? Is anybody else having that problem?

i also have a hard time getting it to work. It completely ignores my ufw allow rules and i have to manually enter stuff into the after.rules to get it working or use a proxy

I confirm that "ufw allow" rules are ignored.

Ah, thank goodness for this issue thread - I thought I was going bonkers 🙃!

Sadly I couldn't get it to work either 😞

Edit: Apologies, I should have been explicit - after following the instructions in the README, like the OP I found that containers were not blocked by default, which was the behaviour I was expecting. I made sure to verify that after running the ufw-docker utility script that the rules were added correctly added to /etc/ufw/after.rules.

It is still working for me.

What is the IP address you use to access it? Maybe you are using an IP address from the IPs declared in the after.rules:

•	192.168.0.0/16
•	10.0.0.0/8
•	172.16.0.0/12

If you access it with one of the internal Docker IPs (which can also be private network IPs), you are bypassing the firewall. If you try accessing it from another network/IP, it should still be blocked.

I am also unable to get this to work. I've installed using the script, but connections are not blocked at all. Have anyone been able to find a fix for this, or know of an alternate solution?

Edit: I forgot to re-remove the trusted IP-addresses from the config after re-installing. Works as intended now.

Block all outgoing connections from inside a docker container except https using firewalld. https://gist.github.com/deploy595/205ea7985fbf41fe66ab9a082021ed6a
