When I go into the Windows Firewall to open up the firewall to allow IP
addresses to connect to the server I see 4 ports listed under file and print
sharing. The 4 ports are TCP 139, TCP 445, UDP 137, and UDP 138. How are
these ports different? Would I need make client IP exceptions for all 4 of
these ports for file sharing?
 
Re: file and print port setup

TCP 445 is all you need if you are running dns. It is the "direct
hosting" port. The others are the Netbios ports and they are all required if
file sharing is using Netbios names.
