    TCP/UDP choices in Firewall

    I've set up port forwarding for UTorrent.

    I now want to adjust my Kerio 2.1.5 firewall settings for Utorrent.

    Utorrent is already permitted in the firewall:

    UDP - in/out - any port
    TCP - in/out - any port.

    My question is: Instead of 'any port' in these situations should I change it to the port I've chosen in port forwarding? If so, do I change ALL of them to the chosen port or just some?

    Thanks for your assistance.

    Jerome in the uT forum's mentioned this:

    TCP - In - [forwarded (local) port] - any distant ports
    TCP - Out - any

    it is enough to work and get green light

    then I would add :

    UDP - Out - any
    UDP - In - [forwarded (local) port] - any distant ports

    You have to set [forwarded port] as a local port not as a distant

    and do not forget to set the same port in uT options

    Local port would mean 127.0.0.1


    I am not that familiar with port forwarding as I use a laptop, though I hope that some of the info I gave you has helped.


    PS: saw your posts in uT forums. Maybe you got the answer there earlier then you may have gotten here, gravale.

    Thanks, SealLion.

    So, when it says eg., TCP - in - [forwarded (local) port], would I insert the port I've chosen (eg. 48500) or 127.0.0.1?

    @SealLion: the "local port" is the one chosen at Options -> Preferences -> Connection.

    @Gravale: I'd say you make the rules these:

    TCP - incoming - your uTorrent listen port (for example, 54345)
    UDP - incoming - your uTorrent listen port

    TCP - outgoing - any port
    UDP - outgoing - any port

    Thanks, anon.

    The following is seen when I click on my Connection tab:

    Personal firewall is running on:

    O Localhost

    O Remote computer (the circle is ticked)

    Host: (empty box)


    Does this seem ok?

    I'm not a Kerio user, so I couldn't tell you, but I think the firewall should be running on localhost (your computer).

    ah, yes. Then I stand corrected re: the local port.

    I think I may have been confused for a moment or 2 thinking that local host and local port are one and the same.
