    Many thanks for these helpful comments. I have a few more questions which I
    hope you can answer!

    1) What happens if the modem is also behind a NAT?
    2) Assuming I modify the router to make myself the dmz machine, does this
    mean my IP address will change in future or will it always stay the same?
    3) Does making myself the dmz have any security implications?

    The whole procedure sounds so long-winded just to get netmeeting working!!!
    How come so many people seem to be using without problems these days? Nearly
    everybody is on broadband so surely everybody must be having this problem?!!
    Maybe other parties are all using dial-up?!
