RTMFP Connection Tester

Having problems connecting RTMFP? Use this application to test NetConnection, NetStream, NetGroup connection and publishing status. For success connection, opened UDP ports in range 1024..65535 required. Run two instances to test NetGroup neighboring.

    I wanted to know in relation to opening the firewall,

    do i need to open the ports for a specific process?
    (like firefox, chrome, IE ?)
    I want to know as i am coding an Addon that may run on FF,IE,CH so
    each of them will need incoming UDP access separately.

    i wanted run an executable at installation time to enable of opening of all the relevant ports in the firewall.
    for now i am in the process of writing this for Windows Firewall.
    but most probably am looking to do the same for Macffee,Norton and AVG…

    drop me an email and i will send u back the code so you could include this on site.

    @Eyal, go through
    first make sure your ISP does not block it by disabling all firewals on your side, after you get connected succesfuly turn on the firewall again and make appropriate changes
