ADSL2 Barricade™ g - 54Mbps Wireless 4-port Broadband Router with built-in ADSL2/2+ modem (Annex A)
With the SMC7904WBRA 4-port ADSL2/2+ router, speeding up for your network has never been easier or more cost-effective. Offering multi-user connectivity many times faster than traditional modems, with leading management and security features that let you take control of your network, the SMC7904WBRA is designed to power the WAN link for your entire office. It comes with 4 built-in 10/100Mbps dual-speed ports and an integrated routing engine that saves you time and money. DHCP automatically configures computers for networking each time one is turned on. NAT lets multiple LAN users share a single ISP account over the ADSL line, eliminating the need to get an account for each person wanting to go online. The SMC7904WBRA includes a firewall with Stateful Packet Inspection, client privileges, and intrusion-detection features that make your internal network invisible to the outside. Virtual Private Networking pass-through (IPSec-ESP Tunnel mode, L2TP, PPTP) is also supported.
