Hi folks,
If it is a FW and a rule based, there are two ways of thinking, the one better than the other. Start with all that is not allowed is blocked or start with all that is not allowed is not blocked.
Some people can have problems at the Win XP firewall too, and that is a one-way thing. Restrictive thinking makes the Internet Connection Sharing add the services there, change the sharing IP to the machine IP.
In howfar people are still hampered by ISPs that do not like filesharing in sofar as they see it as tampering with their bandwidth, which is strange because YOU pay for it.
greets,
