well i am not sure what you are asking, but it uses TCP and/or UDP ports 5000 - 5010 for authenticating in the chat messenger.

Hi kirubaharanbabu,

First of all yahoo and other internet application uses TCP & UDP.

but in case of yahoo uses TCP/IP protocol and his port numbers begins from 5000 to 6000 ports and it is for public use.

Since you are in this TA, and using a router, there are no permissions, all you have to do is set Yahoo to auto recognise the open port.  If you loging in from 192.168.1.1 in set-up on the router, unplug the router, and Modem, the reset the router.  Exit winodws, and re-boot, open the Networking Icon in Contorl Panel for Networking.  Make sure the first item in "Client for Microsoft", then open TCP/IP and the only thing in there sould be on is DCHCP.

Reconnect the router, and the modem and rebood the broad band address will now be static.  And will audo selcet the port 80.

"By default , yahoo messenger connects to port cs.yahoo.com on port 5050...." from http://securityresponse.symantec.com/avcenter/reference/threats.to.instant.messaging.pdf

some googling might help you.

Not obviously guessing wlennon... type "open ports yahoo" into google.

Here is the YAHOO LINK i got that info from and EXACTLY what it states:

http://vc.yahoo.com:5001/

--------------------------------------------------
Information for Network Security Administrators:  
Voice chat data packets are sent by this server using both TCP and UDP. TCP packets that are sent to a user's computer originate from source ports 5000 and 5001. UDP packets that are sent to a user's computer originate from source port 5000 and are addressed to a port in the range 5000-5010 on the user's computer.
Depending on the configuration of your firewall (or other intrusion detection system), during normal use of Yahoo! Voice Chat you may be notified that suspect network traffic is originating from one or more of our servers. Network traffic that meets the parameters described above is normal and does not indicate a scan or attack.

Yahoo! Voice Chat uses the Real-time Transport Protocol (RTP, described in RFC 1889) for communication between users' computers and the Yahoo! voice servers. A firewall must allow a user's computer to make outgoing TCP connections to ports 5000 and 5001 on our servers. The servers will always attempt to use UDP for voice data, but will use TCP if UDP is blocked (your firewall may log the blocked UDP packets).

Current list of Yahoo! Voice Chat servers (subject to change):

    v1.vc.scd.yahoo.com (66.218.70.32)
    v2.vc.scd.yahoo.com (66.218.70.33)
    v3.vc.scd.yahoo.com (66.218.70.34)
    v4.vc.scd.yahoo.com (66.218.70.35)
    v5.vc.scd.yahoo.com (66.218.70.36)
    v6.vc.scd.yahoo.com (66.218.70.37)
    v7.vc.scd.yahoo.com (66.218.70.38)
    v8.vc.scd.yahoo.com (66.218.70.39)
    v9.vc.scd.yahoo.com (66.218.70.40)
    v10.vc.scd.yahoo.com (66.218.70.41)
    v11.vc.scd.yahoo.com (66.218.70.42)
    v13.vc.sc5.yahoo.com (66.218.70.43)
    vc1.vip.scd.yahoo.com (66.218.70.44)

I don't know what happened to my post brfore yours, but I did save the comment.


I have a question, the TA being Routers, meaning connecting to almost any Instant Messaging will auto select port 80, there is no reason to open the software for the router and choose a port.  

bptacek is obvously guessing, and the link D4m0nk posts, on page 6 I believe it mentions port 80.  

That will be the same for AOL IM, Yahoo IM, and MSN IM.  the default in these setups is port 80, and will also default to "No Proxies"

Thanks,
wlennon

I seems to me that you are referring to a Nework Server, which is a wholley differnt animal than a Router, Home based Lan, uging Cable or DSL.  In the above link this time, the title of the post from Yahoo is, and I quote from your artile, "Information for Network Security Administrators:"  "Depending on the configuration of your firewall (or other intrusion detection system), during normal use of Yahoo! Voice Chat you may be notified that suspect network traffic is originating from one or more of our servers. Network traffic that meets the parameters described above is normal and does not indicate a scan or attack."  We are not dealing with a Network.

I am not sure if you are actually using YIM, but I am, and as I look directly at it, it is configured on port 80, and I didn't have to even assign a port as they all searh for Port 80.  On most networks you are correct that you have to open a port in the 5000 range for it to work, such as I did at work.

Respectfully yours,

welnnon

Not trying to argue the point, but I see, what I see.

Yeah I see what you are saying, but I know that in order to transfer files and etc you would have to open those ports.  At least in my experience that is the case.

Either way, kirubaharanbabu was not specific in his question for what he wants, so who knows if any of our info is what he wanted, and he hasn't answered since 2001, so oh well.
