Yes, it should by default. Depends of which IPs/Ports will you filter.
Best regards.

Thanks Costales, I've tried to filter ports 137, 138 and 139 to no effect. Following this link "http://techotopia.com/index.php/Using_gufw_and_ufw_to_Configure_an_Ubuntu_11.04_Firewall#Adding_Advanced_Rules " I tried port 22. I'm still lost as to what I should do and how to do it. Regards Ian.

Hi Costales, I'm a bit lost after doing a lot of reading. With the firewall enabled and no rules installed Firefox and Thunderbird work okay, however looking at gufw
Incoming = deny
outgoing = allow
                                           since incoming is set to deny I would expect all my Internet stuff fail as no IP data grams can enter. I guess I've got my ideas really wrong! Please can you set me right on that? Regards Ian.

I used the above link to fix the problem. The following link is my feedback.
    All that I wanted to do was to exchange files on my three home machines and have the firewall active. I understand the high level of what I've done but the details as to why this is not standard installation or why I needed to fiddle with it to do something really basic I do not understand. By the way with these fixes the pre-configured SAMBA rules worked okay. Ian.

Can you help with this problem?
