1.1 Extended Intranets

The ZyXEL VPN solutions primarily can be used to extend the intranet and deliver increased
connectivity between operation sites. The branch office subnet will be considered a part of
main office internet. Therefore, user behind branch office also can use the internal network
resources as if he was in the main office. Because of the VPN connection, user will feel like he
is using a local LAN even though he is accessing the network resources via Internet. Use of a
VPN for smaller branch offices, franchise sites and remote workers provides nearly the same
level of connectivity and reliability as a private network. The remote connection cost also can
decrease by leveraging the Internet connections to replace expensive leased lines.
