How does NAT/ICS change the picture?



This is a very particular case in that all computers in the LAN will appear to the outside world as having the same IP. We must distinguish between two cases:

1. You are the single XMASTER users in the LAN

You should use the same XMASTER account in all the computers.

Note also that in the ICS case it is preferable to run the BT client on the ICS gateway. Clients running on the other computers will be unconnectable (they will be listed as such, as explained elsewhere in the FAQ) unless you specify the appropriate services in your ICS configuration (a good explanation of how to do this for Windows XP can be found here). In the NAT case you should configure different ranges for clients on different computers and create appropriate NAT rules in the router. (Details vary widely from router to router and are outside the scope of this FAQ. Check your router documentation and/or support forum.)


2. There are multiple XMASTER users in the LAN

At present there is no way of making this setup always work properly with XMASTER. Each torrent will be associated with the user who last accessed the site from within the LAN before the torrent was started. Unless there is cooperation between the users mixing of statistics is possible. (User A accesses the site, downloads a .torrent file, but does not start the torrent immediately. Meanwhile, user B accesses the site. User A then starts the torrent. The torrent will count towards user B's statistics, not user A's.)

It is your LAN, the responsibility is yours. Do not ask us to ban other users with the same IP, we will not do that. (Why should we ban him instead of you?)
