Connecting to WordPress server

Whenever I install WordPress locally with WAMP or XAMPP it seems like it is impossible to connect to wordpress servers.

For example when I go to Themes section I get an error message (http://localhost/sagitshalit/wp-admin/theme-install.php)

ארעה שגיאה בלתי צפויה. משהו יכול להיות לא בסדר עם WordPress.org או עם התצורה של השרת. אם הבעיות ממשיכות להופיע, יש לפנות לפורום התמיכה.

It’s in Hebrew, it translates to:

There was an unexpected error. Something may be wrong with WordPress.org or the configuration of the server. If problems continue to occur, please contact the support forum.

I know exactly why this is happening, I have a firewall blocking everything.
So the WAMP server is active and everything is working fine besides the connection to WordPress server, now, since there is no Service or EXE running in Windows task manager, I need to know which connection to allow through my firewall and I couldn’t find it searching Google.

Do you know which IP:PORT I need to allow for this to work?

Thanks,
