    GUFW Rules

    Hi, I've just set up GUFW as a firewall and I've setup some rules for what it should allow.

    The preconfigured rules only allow you to select from 6 bittorrent clients, skype & ubuntu one to set permissions for. Can I assume from this that that's all I would need to set rules for? If not how do I go about adding other applications. I've checked out the simple & advanced rules tabs & simple gives me the option to write in 'Port or Service' - will it recognise whatever I type in, for example if I want to set rules for TOR or for a distributed computing project what do I need to type into the box?

    Another thing is when I add a rule - say for ubuntu one it displays in the list of rules as "456/udp Allow In Anywhere", etc with no indication as to what rule or port number relates to what application. Doesn't seem to be a way to get it to display Ubuntu One Allow In, etc instead & I can see it becoming very confusing if I need to set a lot of rules. Is there an easy way to make sense of this and to be clear as to what applications rules ar set for?


    By the way I'm on Ubuntu 12.10

    rules are service related for TCP:
    25 SMTP
    80 HTTP
    110 POP3
    443 HTTPS
    67and 68 DHCP
    53 DNS
    53 DNS udp
    are some examples of allowed (if you need them) outbound traffic. the last ones are nec. for internet access.

    I think 67 and 68 are UDP allow out (if you want outbouund ports set to default deny).

    I've not found an application specific firewall for ubuntu.

    There is Leopard Flower - but it has no deb package that I know of - so you'd need to build it.

    What is your plan? Are you using the default setting which is denying all incoming and allowing all outgoing?

    Unless you are running services you do not need to allow any in.

    Thanks guys, looks like I'll just need to keep a note of what ports are for what & what apps are allowed through firewall.
    Yes, I'm blocking all incoming & allowing all outgoing, just allowing bittorrent. Wated to be able to allow other apps like distributed computing but can't see how to.
