Opening A Firewall Port ?

Hello,

I have a program that has two components: RCS and ShortwaveLog) that to work properly together apparently requires the opening, or allowing, for a particularly Port No. of the Windows Firewall.

"If RCS and Shortwave Log are not communicating and you have a software-based firewall, you may need to add a rule to allow TCP port 21687 to pass. This rule need only be applied to localhost (127.0.0.1)."

Have been trying to find what to change, and where, without messing anything else up, but I cannot. The Help File says to click on items that do not appear on the screens (in my PC). Help is probably out of date ?

Might someone please tell me all the explicit steps that I have to go thru, and where to find the items.

(I have the 64 bit version of W7, but not sure whether the program uses the 64 version or not ?)

Much thanks,
Bob

Hello,

All set now.
Thanks for help.

Pretty sure the program I want to use uses TCP.

BTW: just to educate me, what is this UDP ?
e.g., what types of programs use it, or where is it used ?

Thaks again,
Bob
