The included firewall protects against attacks including DoS (Denial of Service) attacks, IP-based attacks and access by unauthorised remote systems. Wireless, Ethernet and VPN are also protected by various protection systems. The latest ('Version 3') DrayTek object-based firewall allows even more setup flexibility than ever, enabling you to create combinations of users, rules and restrictions to suit multi-departmental organisations. The Vigor 2830 now also allows selective direction firewall rules of LAN to WAN, WAN to LAN or LAN to VPN. In addition, QoS (Quality of Service Assurance) can now be selectively applied to specific users.
The Vigor 2830 features a hugely flexible VLAN system. In its simplest form, each of the four Gigabit LAN ports can be isolated from each other, for example to feed four different companies or departments but keeping their local traffic completely separated. For more sophisticated scenarios, the Vigor 2830 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 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 (Vigor2830n / 2830Vn) each of the wireless SSIDs can also be grouped within one of the VLANs.
The Vigor 2860 series is the 2830's bigger brother. This is (including the Vigor 2860n and Vigor 2860Vn) the new router/firewall which can support either ADSL or VDSL (BT Infinity/FTTC). This makes the Vigor 2860 ideal ideal for users with ADSL now who might upgrade to VDSL later. Alternative WAN ports can insead provide connectivity to Ethenet feeds, secondary xDSL modems or a 3G cellular service using a USB adaptor. This latest router series includes support for professional features such as VLAN tagging, Gigabit Ethernet built-in WiFi ('n' models). Packed with professional-level features, the Vigor 2860 series offers truly comprehensive DSL connectivity and security. Compatible with all UK variants of ADSL (including ADSL2+ and Annex M), VDSL and VDSL2, the Vigor 2860 can also be used for cable-modem, leased line and EFM applications using its Gigabit Ethernet WAN port. On VDSL, the Vigor 2860 series supports the very latest services for speeds up to 80Mb/s (depending on line quality and length).
The Content control features of the Vigor 2830 allow you to set restrictions on web site access, blocking download of certain file or data types, blocking specific web sites with whitelists or blacklists, blocking IM/P2P applications or other potentially harmful or wasteful content. Restrictions can be per user, per PC or univeral. Using DrayTek's GlobalView service, you can block whole categories of web sites (e.g. gambling, adult sites etc.), subject to an annual subscription to the Globalview service, which is continuously updated with new or changed site categorisations or sites which have become compromised (such as infected with Malware).
The Vigor 2830 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 Vigor2830n and Vn models includes a hardware co-processor for WiFi which can provide an increase of up to 40Mb/s for WiFi connections compared to our other models. 802.11n provides a total wireless bandwidth of up to 300Mb/s using new methods such as packet aggregation and channel bonding. 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 real world tests). In addition, 802.11n provides greater coverage and resilience to interference compared to previous wireless standards thanks to the MIMO tech
