<![CDATA[Install cups for local network]]>Good evening,

I know and read that I should not configure my firewall, but I run Cloudron at home as a server and on this machine and this place it is only possible to run my Dymo Labelwriter.

How can I configure successfull the firewall to run this idea?

At the moment netstat -tulpen said:

Have a nice evening!

The following rule must be add additionally:

sudo iptables -A CLOUDRON_RATELIMIT -p tcp -m tcp --dport 631 -j ACCEPT
sudo iptables -A CLOUDRON_RATELIMIT -p udp -m udp --dport 631 -j ACCEPT

And my cups conf has follow lines (only an excerpt)

Listen *:631
Listen /run/cups/cups.sock
SystemGroup lpadmin

After that I add my own user during the installation of Ubuntu to group lpadmin to administrate cups and now it works well.

In which chain I must add the rule or what I have to do to access?

sudo iptables -A INPUT -p tcp -m tcp --dport 631 -j ACCEPT
sudo iptables -A INPUT -p udp -m udp --dport 631 -j ACCEPT
sudo iptables -A CLOUDRON -p tcp -m tcp --dport 631 -j ACCEPT
sudo iptables -A CLOUDRON -p udp -m udp --dport 631 -j ACCEPT
