VPN - Linking remote offices, HQ, teleworkers and mobile staff
A feature central to DrayTek routers is the VPN (Virtual Private Networking) features. A VPN enables you to link two remote offices, branch offices back to HQ or home-based/mobile teleworkers back to your office. Once connected, they have access to your office/remote resources through a secure encrypted tunnel allowing remote desktop, file sharing and seamless access to other resources and devices.
The Vigor 2860 allows you to set up up to 32 simultaneous VPN tunnels to remote offices or teleworkers. The Vigor2860 supports all industry standard protocols, including encryption and authentication methods. Teleworkers can authenticate directly with your LDAP server if preferred.
The Vigor2860 supports VPN trunking; this allows you to create tunnels down muliple WAN connections to a remote site in order to increase bandwidth. VPN trunking also provides failover (backup) of your VPN route down a secondary WAN connection. You can learn more about DrayTek VPN here.
The Vigor 2860 also supports SSL VPN. These are encrypted tunnels linking your teleworker back to your main office but they are 'clientless in that your O/S does not need to generate the tunnel and you do not need to install any VPN software manually. You instigate an SSL tunnel from your regular web browser, so it could be in a web cafe or guest network, and the tunnel is creating using SSL technology - the same encryption that you use for secure web sites such as your bank. The Vigor2860 can operate SSL VPNs in either Proxy or full tunnel mode and allows up to 5 simultaneous incoming users. For SSL VPN tunnel mode Windows OS is supported.802.1q Tagged, Wireless & Port Based VLAN
The Vigor 2860 features a hugely flexible VLAN system. In its simplest form, each of the six Gigabit LAN ports can be isolated from each other, for example to feed different companies or departments but keeping their local traffic completely separated. For more sophisticated scenarios, the Vigor 2860 includes tagged VLANs (802.1q) whereby data is marked with a VLAN identifier. This identifier can be read by an onward Ethernet switch and directed to specific ports or just passed to the LAN for specific VLAN clients to pick up; priorities can also be applied for LAN-side QoS.
The VLANs can be tied to any other individual 6 RJ45 ports on the front of the Vigor 2860, or, as seen below, by the use of VLAN tagging, you can uplink to a larger switch and retain the separation for larger groups:
The VLANs can each be tied into each of the different IP subnets that the router may also be operating, to provide even more isolation. On the Wireless-equipped models (Vigor2860n / 2860n-plus) each of the wireless SSIDs can also be grouped within one of the VLANs.
Each individual private subnet can be independent (isolated) or common (able to communicate with each other). This is ideal for departmental or multi-occupancy applications.User Management/Authentication
The Vigor 2860 has built-in user management which allows you to provide internet access to users based on their own unique login (stored in the router, or on an external Radius server). Accounts can be restricted by schedules or maximum usage times but also any other aspect of the firewall or content filtering can be applied on a user-by-user basis. For example, a sales department might not be allowed access to social networking sites except at lunch time, or in a school, teachers and staff have more access permitted than pupils. This works with Wireless (WiFi) clients too so is ideal for guest or temporary access as users can be isolated from the rest of the company LAN.Reliable and High-Performance WiFi ('n' models only)
The Vigor 2860 Series 'n' models feature 802.11n wireless LAN specification and has been certified by the WiFi alliance for cross compatibility and WiFi compliance (including WPA/WPA2 and WMM). The Vigor2860n and Vn models includes a hardware co-processor for WiFi to ensure best performance and encryption processing.
802.11n provides a total wireless bandwidth of up to 200Mb/s using new methods such as packet aggregation and channel bonding. Real-world throughput depends on your own environment (factors such as obstructions, number of hosts and distance all make a significant difference), but actual transfer speeds of over 100Mb/s are achievable (based on our real world tests). In addition, 802.11n provides greater coverage and resilience to interference compared to previous wireless standards thanks to the MIMO technology and the Vigor's antennae diversity arrangement.Wireless Security
The Vigor 2860 Series provides several independent levels of security including encryption (up to WPA2), authentication (802.11x) and methods such as MAC address locking and DHCP fixing to restrict access to authorised users only. The Web interface lets you see how many and which clients are currently connected as well as their current bandwidth usage. An 'instant' block lets you disconnect a wireless user temporarily in case of query. The Wireless VLAN facility allows you to isolate wireless clients from each other or from the 'wired' LAN.
The Vigor2860 wireless versions also allow guest access with password protection so that visitors can use your WiFi access, but only with a password which you set for them. When the user connects to your wireless LAN, they are firstly presented with your login screen before any Internet access is permitted. This is in addition to any encryption system you have running.
The Multiple SSID features enables you to have up to four distinct or common virtual wireless access points. For example, you could have one for company usage, with access to your company LAN and another for public access which allows internet surfing only. Setting up wireless security is made easier thanks to the WPS feature (WiFi protected setup) whereby your client PC can get it's security keys by pressing a button on the front of the router.
For specialist or more demanding coverage applications, optional aerials can be used with the Vigor 2860 to potentially increase the range of wireless coverage (depending on environment) or provide directional coverage in order that your wireless transmission is focussed and concentrated into one direction only, for example into a room or across open space. With the increasing popularity of wireless LANs, you will want to choose the least congested wireless channel (Nos. 1-13) for yours so the Vigor can scan and provide a list of all devices in the vicinity so that you can choose the best channel (see screenshot below).
The Vigor2860n provides a local survey of other devices so that you can choose the least congested channel.

Vigor 2860 'n' models support WDS (Wireless Distribution System) which enables you to use the wireless capability to bridge to another network, within wireless range. You need an additional compatible wireless router for this of course. Here is a simple example:
With WDS bridging, both networks should be within the same logical IP subnet (IP address range). Once set up, all of the PCs on both sides of the link can access each other, across the wireless bridge. Local wireless devices such as a laptop can continue to use their local access point.
An additional mode, as shown above, called 'repeating', allows you to set up a third station. In the diagram below, the router at 'B' is set up in repeating mode, relaying traffic between LANs at A and C. Therefore, all three physical networks can communicate with each other over the wireless links.Important Note: Wireless performance (speed and range) always depends on your specific environment and will vary considerably. Factors affecting performance include wireless traffic, other networks nearby, site construction, walls, ceilings and other electronic equipment nearby. Speeds quoted are the maximum wireless capacity, including RX/TX capacity, protocol overheads and all clients/hosts connected.3G/4G Cellular Data Features
The Vigor 2860 Series' USB port can host a compatible 3G/4G USB modem for access to the cellular network for full Internet Access. All UK networks provide high speed HSDPA data connections and some are starting to roll out 4G.
The 3G/4G connection can be used as your primary/only Internet access, or as backup to your main ADSL line connection. This facility is ideal for homes or offices which don't want to pay fixed line + broadband rental and also for temporary locations, or those to where fixed lines aren't available but for businesses, having 3G as a failover to your main connectivity means that your business stays online when your broadband doesn't!.
With the Vigor 2860n (Wireless model) your local users can be connected wirelessly to the router, so instant free 'hotspots' can be deployed quickly and easily. Mains power is required for the router's PSU, but this could be from a mobile generator or equivalent so you need to plan for this.

The Vigor 2860's USB port can also be used to add storage memory to the unit in the form of a USB memory key (as shown right) or for higher capacity a USB hard drive (normally requires its own power). The Vigor 2860 then provides FTP access file uploading/downloading which can be from the local LAN or from anywhere on the Internet - ideal for a simple to deploy file depository. Access can be 'public' or using usernames and passwords, each of which can have their own directories and/or file access rights. As well as FTP, file sharing is available as a Windows 'network drive'. You can also use Windows Explorer to view and access the contents of the USB drive.
If you do have a USB memory key connected, you can also have the router save it's system logs (syslog) to that memory instead of to a connecting computer; useful for technical personnel (SysAdmins).
The NAS facility uses any FAT32 formatted device (includes USB memory sticks, USB hard drives etc.) and supports a transfer rate of 12Mb/s so ideal for occasional or remote storage.
