Firewall rule to allow access to windows updates

When you try to install Windows updates for the first time (e.g. you buy a new computer with Windows 8.1 preinstalled), windows doesn’t start to download updates unless you permit UDP connection to port 3544.

Here is the firewalling rule for your linux firewall:

iptables -A FORWARD -d -p udp -m udp --dport 3544 -m conntrack --ctstate NEW -j ACCEPT

Here we go!
