Ken (and BCC to Steve S.), I decided to test a few things so I logged into one of my computers with one Yahoo ID and the other with a second Yahoo ID and opened up my Comodo firewall to look at the connections. Here's a rough chronological listing of what happened with YM 10.0. Beta as I made various connections. These connections went to many different IP addresses so I did not log them, just the port info.
Upon opening YM but before signing in: TCP Listening: 1053 Sign-In: TCP Out: 80, 5050, 443, 3478, 3479 (3478 and 3479 eventually disconnected... maybe ads?) Listening: 5101, 1061, 1053 Source: (my IP address - 1059 thru 1100 varying and changing regularly) Webcam turned on: TCP Out: 5100 Listening: 5103 Started Voice Chat (Call): Listening: 1108, 1111, 1113 UDP Out: 9520, 9521, 31920, 31921, 3478 Closed Voice Chat: UDP 31920, 31921, 9520, 9521 stayed open Eventually, after a few minutes of no activity, YM was back down to just: Listening 1053, 1061, 5101 TCP Out: 5050, 443 Signed out and back in: Listening: 1175, 1183, 1188 Started an IM with myself on other computer: Raised incoming/outgoing Bytes activity on: TCP Out: Source: 1181 / Destination: 5050 Sent a bunch of IM's back and forth: Only real Bytes In and Out on: Source/Destination 1181/5050 1227/80 1185/443 All other connections were 0B or 50-100B, not even making it into the KB range. Cam back on: TCP Out: Source: 1233 and 1234 to Destination: 5100 and 5100 Sent Cam Invite: 1250 to 5102 Once connected: 1234 to 5100 (still Listening: 1175, 5101, 1183, 1188, 5103) Shut all connections down except main YM window signed in: Started Voice Call and YM connections went ballistic with about a dozen new connections, most to 80 and other ports that were previously active BUT main Bytes Incoming and Outgoing activity was: UPD Out 23354 to 9532 (which showed constantly increasing incoming and outgoing Bytes as sound went back and forth between the computers) I hope this helps! Unfortunately, I had a brain fart and did not open Comodo firewall on my other computer which had YM 9.0x on it to see which ports were being used on it. I did just peek at the other computer with YM 9.0x and it was Listening on TCP 49913 and 5101 and TCP Out Source: various ports - 49919 thru 50084 to Destination Ports: 5050, 443 and 80 with the connection of 49919 to 5050 being the Incoming/Outgoing ports for IM's being sent to my other computer and all Bytes activity took place with those Incoming and Outgoing ports. A voice call from the 9.0x YM to the 10.0 Beta YM and a BUNCH of connections happened with the primary connection with all of the incoming and outgoing Bytes activity took place on UDP In Source 23364 and Destination 9544. Sorry for less details on the computer with YM 9.0x, but hopefully this gives us all a better understanding on what YM is doing when connecting and responding.

Darn. I was hoping those ports still worked but that page was written back when YM 8.1x was the latest version. I'm guessing that Yahoo must have reconfigured things... BUT read more below. Here is an email address to Sarah Bacon, [email protected], who is the public liaison for Yahoo! Inc., for the Yahoo Messenger team. She is also the one that writes (or at least signs) all of the blogs for YM at http://www.ymessengerblog.com. Try emailing her with this email thread and maybe she can have one of the actual YM engineers/techs provide you with updated port info and please pass that along to me and maybe to the HelpBytes webmaster so they can update their page. Ask about the ports for YM 9.0x and 10.0 Beta as well. If HelpBytes does not want to update their page, then either you or I could create a new page with the updated information. You are more experienced than I am on this type of issue but some thoughts... if you only had one router, would that make a difference or if you block the ports on one or both, it should do the same thing? Did you double-read the info on the HelpBytes page... namely this section about Voice Chat... (START SNIP) Voice Chat UDP 5000-5010 TCP 5000-5001: Client Access If UDP Fails, TCP will be used instead, see below. (END SNIP) You mentioned in your earlier post that you blocked UDP 5000-5010 but did you also block the TCP 5000-5001 ports? Look at that section again and the "see below" sections on the HelpByte site again and also look at the two links to the "graphical example" pages for Linksys and D-Link routers if you have either of these. You didn't mention your router brand(s). I am also BCC'ing an online friend (from another computer tech group) who is more familiar with company networks, as that is his business, and possibly has some insight into blocking certain parts of apps from having internet access... maybe even the specifics needed in this case. I'm guessing a larger company would be more interested in blocking things like this than the average YM or home network user. I'll let you know his thoughts or if he knows the exact solution.

However this did not stop the voice over Yahoo. I should ecplain that I have 2 routers that are cascaded. I have entered the ports to be blocked in both of them and it does not stop the voice service. As I said before, stopping the cam was easy with port 5100. This is proving alot more difficult. --- In [email protected], "LNVTM1 - Lenny Vasbinder" <lnv...@...> wrote: > > I think the info on this page should help you. > > http://www.helpbytes.co.uk/yconnect.php > > Let me know if the instructions work, since I haven't had to do any of > these things yet, but I saved this page a while back as the entire > website has LOTS of good info on tech issues for YM. > > Or.... if you find that something on that page doesn't work but > something you figured out does work, let us know.... or you could > create your own webpage yourself or I could create a blog about the > topic... of course, with credits to you. > > Lenny Vasbinder > http://lennyvasbinder.blogspot.com > FREE and automatic online remote backup of your documents, photos and > files... https://mozy.com/?ref=SY4ZSI Check out how simple and secure > it can be to use the Mozy remote backup system.
