ZyWALL 1050 Support Notes

1.3 Remote Access VPN

Remote Access VPN provides a cost-effective alternative to standard dial-in remote access

to a company network. The users can connect to the network via the Internet, eliminating the

expensive long-distance or the toll-free dial-in costs.

The most common scenario for application might look like this: An employee is on the road

(i.e. teleworker). He can gain full network access simply by connecting to the Internet. During

the data transmission between remote and host, this connection should also provide

confidentiality (Data transferring in VPN tunnel with encryption).

Another genius application is a “Mobile office”: Teleworker or home & SOHO employee

can work at airport, cyber café, hot spots, hotel or home. The office building scope can be

eliminated and a global office can start to fully utilize the global resources.

1.3.1 Remote Access VPN

In this scenario, we assume the ZyWALL1050 admin configured the VPN settings in a way to

allow teleworker access internal network resource through remote access VPN. Since it is

unknown what IP address will the remote teleworker’s PC/notebook connect from, 0.0.0.0 is

used as for ZyWALL1050’s remote gateway setting it represents “any IPs”. On the other end,

the teleworker use ZyWALL VPN client on their notebooks to establish IPSec VPN with the

main office.
