I am trying to organize sharing files and printer-sharing in a home network using Windows7. Microsoft instructions list a number of ports to open, e.g.:
"To find other PCs running earlier Windows operating systems, and to use file and printer sharing on any Windows operating system, open these ports:
UDP 137 UDP 138 TCP 139 TCP 445 UDP 5355"
In order to specify to Comodo Firewall what ports I want open, I should (I believe) create a “portset” and then specify that these ports should be open.
When I open the list of ports in Comodo, before I begin to include specific ports in the new “portset”. The list that Comodo presents to me doesn’t specify whether a port number is UDP or TCP. Does this mean that I should include the ports in the portset simply by number and disregard UDP and TCP as trivial for my purposes here. I have seen a table where certain port numbers are in the same row with both UDP and TCP designations. Does this mean the port is governed by two protocols (and so for my purposes I should only pay attention to the number) or that there are different ports, with the same number, which fall under either one protocol or the other, for example: UDP 5355 would be a different port from TCP 5355.
I think that this must be obvious to most of you, but not to me so far. Thanks for whatever clarification you can offer.
