 Also, if you need a cable, come to the LAB during office hours; we have a couple of them to give. ;) Also, if you need a cable, come to the LAB during office hours; we have a couple of them to give. ;)

 All devices connected with an Ethernet cable get not only an IPv6 address, but a **public IPv4 address** as well, it is therefore necessary to **correctly configure the firewall** on such devices. Alas, people do not, so, unfortunately, we had to close some ports that people commonly leave open by mistake: All devices connected with an Ethernet cable get not only an IPv6 address, but a **public IPv4 address** as well, it is therefore necessary to **correctly configure the firewall** on such devices.

-===== Installation manuals =====+===== How to find a MAC address ===== 
 + 
 +A MAC address is an unique identifier of a network device. It is commonly written as a hexadecimal number, which may look for instance like this: 
 + 
 +''AB:CD:EF:12:A3:04'' or ''AB-CD-EF-12-A3-04''  
 +

-{{indexmenu>:en:verejne:sit:ethernet|tsort nsort}}+If you are unable to find your device's MAC address, come visit us during office and bring your device with you, we are happy to help you. Sometimes, you may find it on the device itself, or it's packaging. On devices with menus, it's commonly found in sections called "Settings" or "About the device".
