Access Via Central Site; Vpn Tunnel To Central Site (Zywall 70 To Zywall 1050/Zywall Usg 300) - ZyXEL Communications ZYWALL 1050 Support Notes

1.5 Access via Central Site

1.5.1 VPN Tunnel to Central Site (ZyWALL 70 to ZyWALL 1050/ZyWALL USG 300)

The idea of this scenario is to redirect all the outgoing traffic originated from the branch
office to the main office via the VPN tunnel so that the network administrator can manage and
control the traffic or apply additional secure access control or inspection.
What is the benefit for deploying ZyWALL1050 in this kind of application?
Insecurity of Internet connectivity
‧ Virus, Bots, spyware, exploits and other forms of attacks are all coming in from
the Internet
‧ As a result, Internet connectivity needs to be securely managed & watched
‧ "Avoid multiple Internet connections in a corporate network" is a common
security practice
What there is a multi-site, distributed corporate network?
‧ Through network planning, centralized Internet connectivity can be achieved
‧ ZyWALL 1050/ZyWALL USG 300 helps you to easily achieve this goal
For the enterprise security and performance consideration, we can also separate the VPN
and internet connection loading and send it through different security gateways. Thus, all
VPNs connected to the VPN gateway can apply the VPN concentrator role; the internet
connection gateway will focus on the internet connection and perform all layer7 security
inspection. By doing this, we can achieve good level of security while the total network
throughput and performance remains high.
