    hi all,

    i'd like to allow my internal network to use yahoo
    voice chat. in order to do so, i must add some
    iptables rules in my firewall. so i went to yahoo's
    troubleshooting page
    (http://help.yahoo.com/help/us/mesg/twin/twin-36.html)
    to find out what ports are needed for the thing to
    work. here it is :

    Voice Chat Connection:

        * Protocol: UDP or TCP
        * Servers:
              o v1.vc.scd.yahoo.com
              o v2.vc.scd.yahoo.com
              o v3.vc.scd.yahoo.com
              o v4.vc.scd.yahoo.com
              o v5.vc.scd.yahoo.com
              o v6.vc.scd.yahoo.com
              o v7.vc.scd.yahoo.com
              o v8.vc.scd.yahoo.com
              o v9.vc.scd.yahoo.com
              o v10.vc.scd.yahoo.com
              o v11.vc.scd.yahoo.com
              o v13.vc.sc5.yahoo.com
              o vc1.vip.scd.yahoo.com
        * Ports: 5000-5010

    after reading the page, i have a question that you
    guys out there might help me. why does it has so many
    servers? what is the benefit? do i have to write 14
    iptables rules for this voicechat to work?

    thank you.

    regards,
    gregor
