Ok, i try some other soft like Eyeball or PalTalk and they work as well as MSN . webcam, voice and chatting all this features are involved. in the other hand we can control the port that will be used by this tools, but in MSN it use dynamic port and with upnp you must open several port. So i hope that user will be comprehensive, if not SIP or H323 standard have to change . we create computer science not to complicate our life :) -----Message d'origine----- De : Carlos Santos [mailto:csantos@xxxxxxxxxxx] Envoyé : lundi 6 octobre 2003 12:46 À : netfilter@xxxxxxxxxxxxxxxxxxx Objet : RE: MSN throught Linux Hi, I've been trying (on and off, on my spare time) to get my firewall (RedHat 9 Shrike) to allow MSN, Netmeeting and Yahoo webcam conversations to take place. I've been keeping up with some of the threads that have been started lately about this subject and what I would like to know before going any further is: is UPNP a security risk ? I don't want to end up with a vault like front door and have all the back windows and doors wide open with "come on in" signs, if you know what I mean. I do want be able to connect to other users with webcams but not at the expense of security provided by the firewall. Please let me know what your thoughts are on this, please. Thanks, Carlos. ***************************************** Carlos Santos csantos@xxxxxxxxxxx *****************************************
