v1.0, January 2010
Extensive Protocol Support
The SRXN3205 supports the Transmission Control Protocol/Internet Protocol (TCP/IP) and
Routing Information Protocol
(RIP). For further information about TCP/IP, see the document that
you can access from “TCP/IP Networking Basics” in Appendix C.
• IP Address Sharing by NAT. The SRXN3205 allows many networked PCs to share an
Internet account using only a single IP address, which may be statically or dynamically
assigned by your Internet service provider (ISP). This technique, known as NAT, allows the
use of an inexpensive single-user ISP account.
• Automatic Configuration of (Wired & Wireless) PCs by DHCP. The SRXN3205
dynamically assigns network configuration information, including IP, gateway, and domain
name server (DNS) addresses, to PCs on the LAN and Wireless LAN using the Dynamic Host
Configuration Protocol (DHCP). This feature greatly simplifies configuration of PCs on your
local network.
• DNS Proxy. When DHCP is enabled and no DNS addresses are specified, the SRXN3205
provides its own address as a DNS server to the attached PCs. The SRXN3205 obtains actual
DNS addresses from the ISP during connection setup and forwards DNS requests from the
LAN.
• PPP over Ethernet (PPPoE). PPPoE is a protocol for connecting remote hosts to the Internet
over a DSL connection by simulating a dial-up connection. This feature eliminates the need to
run a login program such as EnterNet or WinPOET on your PC.
• Quality of Service (QoS). Support for traffic prioritization.
Advanced VPN Support for Both IPsec and SSL
The SRXN3205 supports IPsec and SSL virtual private network (VPN) connections.
• IPsec VPN delivers full network access between a central office and branch offices, or
between a central office and telecommuters. Remote access by telecommuters requires the
installation of VPN client software on the remote computer.
– IPsec VPN with broad protocol support for secure connection to other IPsec gateways and
clients.
– Bundled with the single-user license of the NETGEAR ProSafe VPN Client software
(VPN01L)
– Supports up to 5 (max) IPsec VPN tunnels (alternately, 4 IPsec VPN tunnels concurrently
with 4 SSL VPN sessions, or 5 IPsec VPN tunnels concurrently with 3 SSL VPN
sessions). The total number of concurrent tunnels and sessions is not to exceed eight.
