In the Microsoft Knowledge Base Article - 179442 They mention:
"Alternatively, you can establish a trust through the Point-to-Point Tunneling Protocol (PPTP) compulsory tunnel, and this will limit the number of ports that the firewall will need to open. For PPTP, the following ports must be enabled:
Client Ports Server Port Protocol
1024-65535/TCP 1723/TCP PPTP "
Can anyone explain to me how to do this because Our firewall cannot have all the microsoft ports open which are outilined earlier in the same article.
