Working with Bordermanager 3.8 (HTTP Proxy + packet filtering)
Cannot work with MSN 7.5 (work but only if I suppress packet filtering...)
So, I have to open some ports

Three questions

1) Is somebody know the basic port to open for MSN 7.5
2) Do I have to open port with source=private interface or source =
public interface
3) What are the destination port ?

Thank if somebody can help
