Hello all, I need to restrict a computer hooked up to my network so that it can only access net-bios ports (137-139 I believe). I idea is to let them transfer files and use network printers but nothing else. The computer will have a set IP address. Does anyone know what the exact IPTables line would look like to accomplish this. I have never addressed an issue like this with IPTables. If you do respond could you clarify what the line is doing exactly so that I can modify it to meet this and possibly other needs. Thanks, Doug
