Hello,
I installed on my debian machine over snap lxd.
I have two containers, one a nginx proxy the second a nginx webserver with some static content.
Everything works perfectly and I reached my site from outside over port 80 and 443.
Now I tried to enable my firewall (ufw) with this commands:
ufw default deny incoming
ufw default allow outgoing
ufw allow ssh
ufw allow http
ufw allow https
ufw enable
When I do this, I can still reach my site but in the container I can not update the system with apt-get update
or reach the internet.
What am I missing here? And how can I fix it to use a firewall on my host system.
