Hello all,
I have a work desktop plugged into the work network. As I opened my firewall settings I noticed that it is turned off.
My question is how should I configure it? I saw that the interface isn’t assigned to any zone… I should assign to internal zone and open some port that I need in order to work?
There are some guidelines for configuring the firewall?
Thanks
Simple answer:
Not, just leave it off.
More complicated answer:
Decide which services you want to offer, switch all other services you don’t want to offer off and leave the firewall off.
Even more complicated answer:
Start reading the documentation (the “Help” button in YaST comes to mind, also /etc/sysconfig/SuSEfirewall2 is well documented), then decide which services you want to offer, switch all other services you don’t want to offer off, turn the firewall on and open the ports you need (and then ask yourself why you need a firewall and did all the extra work and decide if you still need it).
Or you could also just leave it off (with the same effect), the reason why is explained in the documentation.
Yes, if you don’t exactly know why you need it and what for, leave it off and start configuring your system to offer only the services you explicitly want to offer, so that you don’t need a firewall in the first place, then decide if you still need one.
