@Joschi - steht doch oben )) NPF
Also die NPF hat es nunmal so an sich, daß sie auch arbeitet, wenn sie deaktiviert ist. Ich sags mal auf Englisch: NetMeeting and Firewalls You can configure firewall components in a variety of ways, depending on your organization's specific security policies and overall operations. While most firewalls are capable of allowing primary (initial) and secondary (subsequent) Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) connections, they might be configured to support only specific connections based on security considerations. For example, some firewalls allow only primary TCP connections, which are considered the most secure and reliable. To enable NetMeeting 3 multipoint data conferencing—program sharing, Whiteboard, Chat, file transfer, and directory access—your firewall only needs to pass through primary TCP connections on assigned ports. NetMeeting audio and video features require secondary TCP and UDP connections on dynamically assigned ports. Therefore, if you establish connections through firewalls that accept only primary TCP connections, you will not be able to use the audio or video features of NetMeeting. Establishing a NetMeeting Connection with a Firewall When you use NetMeeting to call other users over the Internet, several IP ports are required to establish the outbound connection. The following table shows the ports, their functions, and the resulting connection. Port Function Outbound Connection 389 Internet Locator Service (ILS) TCP 522 User Location Service TCP 1503 T.120 TCP 1720 H.323 call setup TCP 1731 Audio call control TCP Dynamic H.323 call control TCP Dynamic H.323 streaming Real-Time Transfer Protocol (RTP) over UDP If you use a firewall to connect to the Internet, it must be configured so that the IP ports are not blocked. To establish outbound NetMeeting connections through a firewall, the firewall must be configured to do the following: Pass through primary TCP connections on ports 389, 522, 1503, 1720, and 1731. Pass through secondary TCP and UDP connections on dynamically assigned ports (1024-65535). The H.323 call setup protocol dynamically negotiates a TCP port for use by the H.323 call control protocol. Also, both the audio call control protocol and the H.323 call setup protocol dynamically negotiate UDP ports for use by the H.323 streaming protocol, called the Real-Time Transfer Protocol (RTP). In NetMeeting, two UDP ports are determined on each side of the firewall for audio and video streaming, for a total of four ports for inbound and outbound audio and video. These dynamically negotiated ports are selected arbitrarily from all ports that can be assigned dynamically. NetMeeting directory services require port 389. Microsoft Internet Locator Service (ILS) servers, which support the Lightweight Directory Access Protocol (LDAP) for NetMeeting, also require port 389. __________ powered by http://different-thinking.de - Netze, Protokolle, Sicherheit, ...

Hallo
es liegt an deiner Firwewall es würde gehen wenn du eine firewall hast wo du einstellen kannst ob du dies erlauben möchtest oder nicht schau doch mal bei http://www.foncall.de nach da findest du einiges darüber liebe Grüße Laura http://www.lauracam.de |

wie kriegt man das netmeeting zum laufen? habe win98, sgeht mir nur um voice-connection, nicht video.
thx4any help

ps:das verrückte ist, dass sobald die FW installiert ist, läufts nicht mehr, sogar wenn ich sie deaktiviere. erste bei der kompletten deinstallation gehts wieder. bin aber kein crack in sachen ports etc.
