Maybe a "beginners" question:

on the download-site it says:
------
I'm connecting through a Firewall / Router-Firewall. What Ports do i need?

To make sure your Firewall does not block any access to Neocron's services, turn it off for a short while and try to log into the game in that time. If you use a Firewall, make sure that the following ports are open for Neocron Community Edition (NeocronClient.exe):

TCP/IP: 7000, 8020, 8040, 12000, 13000

UDP: 6000, 6001, 5000 - 5016

I am using windows defender as firewall where I can open ports for incoming and outgoing connections.
Do I need to open the above mentioned ports for both types of connections?
