If you close port 6346 on your router ... its pretty much a gurantee that no gnutella client will reach the internet, unless of course you have users with dialup modems on their pc, and an ISP account (e.g. AOHell). Personally ... if I were the netadmin ... I'd setup up win2k server with IIS ... set up a simple website or ftp site with the information you want to share as downloadable links. That way you are certian to restrict user access to your 411 ... and if you have port 21 closed on your firewall ... no one will be able to get to that from the outside either ... or if you dont have access to the firewall ... set the internal share port to be something different ... but then you run the risk of someone scanning your network with a port sniffer and finding it anyway .... the choice is yours ... but for the security of "confidential doccuments" that you intend to share on a network ... almost purpose defeating ... IIS or some other sort of server is the way to go.
