iptables ubuntu BLOCK all

If I comment the line pre-up iptables-restore < /etc/iptables.up.rules on /etc/network/interfaces my site works fine. If not everything is blocked.
The content of the file is (just for test)
iptables -P INPUT ACCEPT
iptables -P OUTPUT ACCEPT
iptables -P FORWARD ACCEPT

What I´m doing wrong

Hi, I'm not sure how well adept you are with iptables, but if you're looking for something easier to manage iptables you could opt for the UFW (uncomplicated Firewall) frontend to iptables.

A simple
sudo apt-get install ufw

Open in new window


Should install it.

Then add some default policies like:
    sudo ufw default deny incoming
    sudo ufw default allow outgoing

Open in new window


And some default connections:
sudo ufw allow ssh
sudo ufw allow http
sudo ufw allow https

Open in new window


After this you can enable the firewall (make sure you have another session open or keep this one open and test if you can still access your server via ssh after enabling the firewall).

sudo ufw enable

Open in new window


Check the status of the firewall like so:

sudo ufw status

Open in new window

or
sudo ufw status verbose

Open in new window


These are the basics of course, but should get you going.
