  • VPN Server – lets remote users access the resources on the internal network through their local Internet connection (Windows/XP can connect out of the box).
  • Office Interconnect – combined IPsec VPN server and client allows secure office interconnect.
  • Versatile Wireless Access Point – 802.11b/g (2.4 GHz) and 802.11a (5 GHz) with antenna diversity for extended range at up to 108 Mbps.
  • Wireless Security – WEP, WPA or IEEE 802.11i prevents unauthorized access.
  • Network Address Translation – lets all computers on the internal network share a single Internet connection.
  • Local Domain server – speeds up DNS lookups and resolves local domains.
  • Dynamic Host Configuration server – allows computers on the internal network to automatically configure their network interface.
  • Network Time Protocol server – keeps the clocks of computers on the internal network in sync.
