ADSL2+ 防火牆2 WAN(1 RJ-11 & 1 RJ-45) / 4 LAN+QoS+VPN(32路)+USB Print Port+Wireless(802.11n)+2FXS
Vigor2820n 為一台雙 WAN口之 ADSL2+ 路由器,第二個 WAN 口可以連接 DSL/Cable 數據機或是光纖媒體轉換器,提供條件式規則負載平衡、斷線備援與隨選頻寬功能,另外它還提供進階頻寬管理機制諸如 QoS、連線數的控制、頻寬互借等等,讓用戶更易上手。
| ||
雙 WAN 應用 | ||
| ||
VPN 防火牆應用 | ||
Vigor2820Vn 支援 32 條 VPN 通道並使用 IPSec / PPTP / L2TP / L2TP over IPSec with AES / DES / 3DES 協定加密資料,利用MD5 / SHA-1 驗證資料。
| ||
| ||
無線應用 | ||
Vigor2820Vn 符合 IEEE802.11n 標準,支援 WEP / WPA / WPA2 加密以及 MAC 位址控制、無線區域網路隔離、 多重SSID 以及 802.1x 驗證等等。無線流量控制功能可調整資料傳輸至無線用戶端的速率, WDS 功能可幫助用戶擴充無線覆蓋範圍。 | ||
| ||
VoIP 應用 | ||
Vigor2820Vn 提供二個類比電話孔以及一個線路連接埠,可同時支援數個 SIP,設定容易操作方便。 您可連接一般的類比線路 (PSTN/POTS*) 至 Vigor2820Vn 的 Line 連接埠上,當您啟用 VoIP 功能時,您可撥打 #0 以使用固定線路(類比線路),連接到 Line 及 FXS 連接埠的話機可以用來撥打 POTS 及 VoIP 電話,因為所有的來電都會自動切換至相應之話機上。結果,與路由器相連的類比電話即可讓您使用 VoIP 和類比線路,再者,您可以設定數字對應設定功能,讓一些特殊電話可指定使用 SIP / VoIP 服務或是 POTS 線路,例如,鑒於國際電話撥打者可能透過您喜愛的 VoIP 供應商撥打電話給您,您即可以透過 PSTN 線路由本機電話,設定多個數字對應可讓 VoIP 電話更便利,同時費用更節省。 | ||
| ||
CSM (數位內容安全管理) / 3.5G 斷線自動備援 應用 | ||
Vigor2820 系列的數位內容安全管理 (CSM)功能可封鎖選定的點對點 (P2P) 及即時通訊 (IM) 之應用。不但可幫助員工專注其工作,還能防止這些應用可能內藏病毒,造成公司資料伺服器損害等威脅。 | ||
