Make ufw follow iptable rules












1















I have a bunch of configuration in ufw that I want to avoid porting to iptables (unless there is a easy way to export from ufw and import in iptables). Simplicity of ufw etc. being the reason.



Now I want to block outgoing network for a user on the system using - How to disable internet for a user on a system



But the problem is that if I have ufw enabled, it ignores iptable rules.



How do I ask ufw to follow iptable rules as well or maybe implement that user block in ufw?

Following @aplaice's comment, I added the following line in /etc/ufw/after.rules



-A ufw-after-output -m owner --uid-owner idea -j REJECT
# don't delete the 'COMMIT' line or these rules won't be processed
COMMIT


You have to add it for the chain ufw-after-output and before COMMIT.



Restart ufw service after that.
