I've connected 2 PC's with a crossover cable, and have imported the File Sharing rules (as found on LnS website). I'm also using Phant0m's rule-set. When I click on My Network Places->Mshome in Explorer, an error is displayed saying "Mshome" is not accessible and the LnS log is showing: "Block: All other packets" UDP 255.255.255.255 Ports Dest 137 Src 137 The UDP: Share rule that was imported already covers ports 137-139, but only allows for source and destination addresses of 192.168.0.0 with a mask of 255.255.0.0. What is the best way to solve this problem to allow for UDP communication on ports 137-139 with IP address of 255.255.255.255 (ie. can the current rule be modified, or should I just create a new rule) ? BTW, is this kind of UDP communication is normal for file sharing as it's not allowed in the standard file sharing rule ?
