Of protection provided by the Net's internal properties in addition to many routers, hardware-based firewall's configuration.

Firewall potential very sensitive to the basic equipment can. The TCP / UDP for the game, chat services allow the router, and

the most important work in the LAN behind the firewall in the form of.

So, in an Ethernet network segment with a short line, a router and a switch more efficiently routing multiple network

functions and / or van, as well as TCP / IP packet, and more across the Natural can multiple Ethernet segment may be.
