I'm using a fast PC with XP home and my Router is a Netgear DG834 V2 with the latest firmware. Twice in April we managed a video conference link with the US with no chnages to the ports. After that our contact changes is Mac op system to Tiger OX 10.4. Since that date we meke contact with text messages but no talk and no video either with or without all the correct ports open and yes UPNP is active.
Has any using this setup been able to make AIM work through PlusNet who tell me that all the ports I asked about are open??
