Introduction

Security Features

Password - protected Configuration. Optional password protection is provided to prevent unauthorized users from modifying the configuration data and settings.

NAT Protection. An intrinsic side effect of NAT (Network Address Translation) tech- nology is that by allowing all LAN users to share a single IP address, the location and even the existence of each PC is hidden. From the external viewpoint, there is no network, only a single device - VRT-311 / VRT-311S.

Stateful Inspection Firewall. All incoming data packets are monitored and all incom- ing server requests are filtered, thus protecting your network from malicious attacks from external sources.

Protection against DoS attacks. DoS (Denial of Service) attacks can flood your Internet connection with invalid packets and connection requests, using so much bandwidth and so many resources that Internet access becomes unavailable. VRT-311 / VRT-311S in- corporates protection against DoS attacks.

Rule-based Policy Firewall. To provide additional protection against malicious pack- ets, you can define your own firewall rules. This can also be used to control the Internet services available to LAN users.

IPSec VPN Gateway Features

IPSec.. Support for IPSec standards, including IKE and certificates.

Tunnels. Up to 100 VPN tunnels can be created for VRT-311, and up to 10 VPN tunnels can be created for VRT-311S..

High performance. High performance encryption engine maintains high throughput even when using 3DES.

Microsoft VPN Gateway Support

PPTP Server. VRT-311 / VRT-311S emulates a Microsoft PPTP VPN Server, allowing clients to use the Microsoft VPN client provided in Windows.

Windows Client Support. Remote users can use the Microsoft VPN client (VPN Adapter) provided in recent versions of Windows.

Easy Setup. For both the Administrator and remote users, the Microsoft VPN is much easier to configure than IPSec VPN.
