While Jerome's suggestions is valid, it can be a headache in maintenance. Please take this as a suggestion. :-) Each user purchase a VPN router and establish static addresses with their Internet Service Providers. The costs for both the router and service has come down substantially in the past year. This also provides better security with firewalls and encryption. Lastly, nobody wants the extra effort of maintaining the connection on a dynamic connection and it will happen.
Best of luck. ~Tony -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Jerome R.

Here the situation: You can dynamic or static ip addresses. ======================================= This is (more or less) easy to diferentiate, if the machine is autoconfigured, it dynamic, otherwise it is configure static and you have to type in the address. (Note that some place give out static ip addresses via the automaitc setting)... This creates problems with people trying to connect to you since they have no way of knowing your current address. Solutions: 1) If the other party, has a static address, you can initiate the connection from the "dynamic address" machine. This can be done for both client and server. 2) Use a Dynamic DNS service (DDNS). This solution is better, Here you add to your connection scripts a little program that registers you current address dynamically, to a DNS service. Once done, you can get your IP address from that service. There are free service that do this for you. This is the only solution when both parties have dynamic addresses. But there is another problem you didn't ask, namely.... You can have a local address, or a global address ================================================= Some addresses are not allowed to be transported via the internet. This is done so that the addresses can be reused many times in diferent locations. If this was not so the internet would have run out of addresses a long time ago. The most often used local address ranges are: 10.x.x.x, and 192.168.x.x If your address is one of the above, nobody can connect to you, since the address will not be transmitted via internet. Here the solutions get complicated, you need to preconfigure the NAT/Routesr to understand the situation and do address translatioin for you. This is usually not do-able since this requires extensive support from your provider, and most are not willing to do it. So the solutions are: 1) if only one party has a local address, always initiate the connection from that machine. 2) if both parties have a local address, and you cannot have the NAT/Routes configured for you), or you need to initiate a connect to a local address You need the help of a "Bouncer". A "Bouncer" has a fixed global address, so both sides can always connect to it. It receives the connections from both sides and connects them. Unfortunatetly, all bytes sent go into and out agian from the bouncer. And since the number of bytes you send to/from the internet cost, the bouncer must recover this cost. GoToMyPc is a such a bouncer... Hope this helped your understanding...
