| WAN | 2-port 10/100 base-TX Ethernet | ||||
| USB | 1-port USB 1.1 | ||||
| WAN Protocol | Ethernet | PPPoE, PPTP, DHCP client, static IP, L2TP, BPA | |||

|
|||
| Bandwidth on Demand | service/IP based preference rules or auto-weight | ||||
| VPN | Protocols | PPTP, IPSec, L2TP, L2TP over IPSec | |||
| Up to 200 sessions simultaneously | LAN to LAN, remote access (teleworker-to-LAN), dial-in or dial-out | ||||
| VPN Trunking | VPN load-balancing and VPN backup | ||||
| SSL VPN | Allow users to use a web browser for secure remote user login tunnel mode, application mode, proxy mode and SSTP | ||||
| LDAP | Lightweight directory access protocol. The enterprises use LDAP authentication technology to allow administrator, IT personnel and users to be authenticated when trying to access company's intranet environment. | ||||
| VPN Throughput | 50Mbps | ||||
| NAT-Traversal (NAT-T) | VPN over routes without VPN pass-through | ||||
| PKI certificate | Digital signature (X.509) | ||||

| Authentication | Hardware-based MD5, SHA-1 | ||||
| Encryption | MPPE and hardware-based AES/DES/3DES | ||||
| RADIUS Client | Authentication for PPTP remote dial-in | ||||
| DHCP over IPSec | Because DrayTek add a virtual NIC on the PC, thus, while connecting to the server via IPSec tunnel, PC will obtain an IP address from the remote side through DHCP protocol, which is quite similar with PPTP | ||||
| Dead Peer Detection (DPD) | When there is traffic between the peers, it is not necessary for one peer to send a keep-alive to check for liveness of the peer because the IPSec traffic serves as implicit proof of the availability of the peer | ||||
| Smart VPN software Utility | Provided free of charge for teleworker convenience ( Windows environment) | ||||
| Easy of Adoption | No additional client or remote site licensing required | ||||
| Industrial-standard Interoperability | Compatible with other leading 3rd party vendor VPN devices | ||||
| Firewall | Stateful Packet Inspection (SPI) | Outgoing/Incoming traffic inspection based on connection information | |||
| Content Security Management (CSM) | Appliance-based gateway security and content filtering | ||||
| Multi-NAT | You have been allocated multiple public IP address by your ISP. You hence can have a one-to-one relationship between a public IP address and an internal/private IP address. This means that you have the protection of NAT(see earlier) but the PC can be addressed directly from the outside world by its aliased public IP address, but still by only opening specific ports to it (for example TCP port 80 for an http/web server) | ||||
| Port Redirection | The packet is forwarded to a specific local PC if the port number matches with the defined port number. You can also translate the external port to another port locally | ||||
| Open Ports | As port redirection (above) but allows you to define a range of ports | ||||
| DMZ Host | This opens up a single PC completely. All incoming packets will be forwarded onto the PC with the local IP address you set. The only exceptions are packets received in response to outgoing requests from other local PC or incoming packets which match rules in the other two methods. The precedence is as follows : Port Redirection > Open Ports > DMZ |
||||
| Policy-based IP Packet Filter | The header information of an IP packet (IP or MAC source/destination addresses; source/destination ports; DiffServ attribute; direction dependent, bandwidth dependent, remote-site dependent | ||||
| DoS/DDoS Prevention | Act of preventing customers, users, clients or other computers from accessing data on a computer | ||||
| IP Address Anti-spoofing | Source IP address check on all interface: only IP address classified within the defined IP networks are allowed | ||||
| Object-based Firewall | Utilizes object-oriented approach to firewall policy | ||||
| Notification | E-mail alert and logging via syslog | ||||
| Bind IP to MAC Address | Flexible DHCP with 'IP-MAC binding | ||||

| Printer Sharing | |||||
| Content Filter | URL Keyword Blocking |
Whitelist and Blacklist, Java applet, cookies, active X, compressed, executable, multimedia file blocking
|
|||
| Web Content Filter | Dynamic URL filtering database | ||||
| Time Schedule Control | Set rule according to your specific office hours | ||||
| System Management | Web-based User Interface ( HTTP/HTTPS) | Integrated web server for the configuration of routers via Internet browsers with HTTP or HTTPS | |||
| Draytek's Quick Start Wizard | Let administrator adjust time zone and promptly set up the Internet (PPPoE, PPTP, Static IP, DHCP) | ||||
| User Administration | RADIUS user administration for dial-in access (PPP/PPTP) | ||||
| CLI (Command Line Interface, Telnet/SSH) | Remotely administer computers via the telnet | ||||
| DHCP Client/Relay/Server | Provides an easy-to configure function for your local IP network | ||||
| Dynamic DNS | When you connect to your ISP, by broadband you are normally allocated an dynamic IP address. i.e. the public IP address your router is allocated changes each time you connect to the ISP. If you want to run a local server, remoter users cannot predict your current IP address to find you | ||||
| Administration Access Control | The password can be applied to authentication of administrators | ||||
| Configuration Backup/Restore | If the hardware breaks down, you can recover the failed system within an acceptable time. Through TFTP, the effective way is to backup and restore configuration between remote hosts | ||||
| Port-based VLAN | Create separate groups of users via segmenting each of the Ethernet ports. Hence, they can or can't communicate with users in other segments as required | ||||
| Built-in Diagnostic Function | Dial-out trigger, routing table, ARP cache table, DHCP table, NAT sessions table, data flow monitor, traffic graph, ping diagnosis, trace route | ||||
| NTP Client/Call Scheduling | The Vigor has a real time clock which can update itself from your browser manually or more conveniently automatically from an Internet time server (NTP). This enables you to schedule the router to dial-out to the Internet at a preset time, or restrict INternet access to certain hours. A schedule can also be applied to LAN-to-LAN profiles (VPN or direct dial) or some of the content filtering options | ||||
| Firmware Upgrade via TFTP/HTTP/FTP | Using the TFTP server and the firmware upgrade utility software, you may easily upgrade to the latest firmware whenever enhanced features are added | ||||
| Remote Maintenance | With Telnet/SSL, SSH (with password or public key), browser (HTTP/HTTPS). TFTP or SNMP, firmware upgrade via HTTP/HTTPS or TFTP | ||||
| Wake On LAN | A PC on LAN can be woken up from an idle/stand by state by the router it connects when it receives a special 'wake up' packet on its Ethernet interface | ||||

| Dynamic Routing | It is with routing protocol of RIP v2. Learning and propagating routes; separate settings for WAN and LAN | ||||
| Static Routing | An instruction to re-route particular traffic through to another local gateway, instead of sending it onto the Internet with the rest of the traffic. A static route is just like a 'diversion sign' on a road | ||||
