Data features

Routing

■Network Protocols: IP routing

■Dynamic Host Conﬁguration Protocol (DHCP) Server (RFC 2131), Client (RFC 2131) and Relay Agent (RFC 1542)

■NAT/NAPT: (Network Address and Network Address Port Translation (RFC 1631) Port Translation allows mail, Web, PPTP, IPsec and other servers on the LAN to be accessible from the Internet

■MultiNAT: Sophisticated NAT extension that provides security of a NAT “wall” to hide LAN IP addresses on LAN while providing ﬂexible use of all addresses offered by an ISP

■RADIUS Client support for authenticating system conﬁguration access

■Built-in Firewall: Pre-conﬁgured ﬁrewall to disallow all inbound trafﬁc originated from the internet; Includes IP ﬁltering; Filter packets on a per-connection proﬁle basis for source/destination address, service, and protocol. Up to 255 rules in up to 8 ﬁlter sets.

■Secure VPN: ATMP client and server, PPTP client (PAC) and server (PNS), PPTP NAT pass through, IPSec with DES
