*****

Nowhere in the doc for my modem router can I find anything on
restricting ports for LAN addresses.

My modem router is a netcomm nb1300+4

and I am using scanline to run the scans

How do I control which ports are accessable between PCs on the LAN?

Can anybody shed any light on this for me?

Thanks

Bruce
