Internet Connection Sharing and VNC Port problems

[ebau]

Greetings all,

Have read through the notes and found myself at M$ support looking up the
registry settings to open up the ports closed by M$ ICS. By temporarily
disabling ICS it allowed me to connect with VNC and open up ports as per
documented link below..

This worked for VNC as I opened a whole block between 5000-6000 , but now
seems ICS wont share to the local clients. Should I be restricting and
narrower block ports to  to 5800-5810 and 5900-5910 ? Have I clashed with
another port between 5000-6000 that has halted the normal ICS sgharing
locally?

Any help would be gratefully appreciated
