file and print port setup

[Guest biff]

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?

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.
