VoIP/(802.11g) ADSL2+ (VPN) Firewall Router
Chapter 4: Configuration

After 100 seconds, the device will automatically logout User A.
Universal Plug and Play (UPnP)
UPnP offers peer-to-peer network connectivity for PCs and other network devices, along with control and
data transfer between devices. UPnP offers many advantages for users running NAT routers through
UPnP NAT Traversal, and on supported systems makes tasks such as port forwarding much easier by
letting the application control the required settings, removing the need for the user to control advanced
configuration of their device.
Both the user’s Operating System and the relevant application must support UPnP in addition to the
router. Windows XP and Windows Me natively support UPnP (when the component is installed), and
Windows 98 users may install the Internet Connection Sharing client from Windows XP in order to
support UPnP. Windows 2000 does not support UPnP.
Disable: Check to disable the router’s UPnP functionality.
Enable: Check to enable the router’s UPnP functionality.
UPnP Port: Its default setting is 2800. It is highly recommended for users to use this port value. If this
value conflicts with other ports already being used you may wish to change the port.
SNMP Access Control (Software on a PC within the LAN is required in order to utilize this function) –
Simple Network Management Protocol.
SNMP V1 and V2:
Read Community: Specify a name to be identified as the Read Community, and an IP address. This
community string will be checked against the string entered in the configuration file. Once the string name
is matched, user obtains this IP address will be able to view the data.
Write Community: Specify a name to be identified as the Write Community, and an IP address. This
community string will be checked against the string entered in the configuration file. Once the string name
is matched, users from this IP address will be able to view and modify the data.
Trap Community: Specify a name to be identified as the Trap Community, and an IP address. This
community string will be checked against the string entered in the configuration file. Once the string name
is matched, users from this IP address will be sent SNMP Traps.
SNMP V3:
Specify a name and password for authentication. And define the access right from identified IP address.
Once the authentication has succeeded, users from this IP address will be able to view and modify the
data.
SNMP Version: SNMPv2c and SNMPv3
SNMPv2c is the combination of the enhanced protocol features of SNMPv2 without the SNMPv2 security.
The "c" comes from the fact that SNMPv2c uses the SNMPv1 community string paradigm for "security",
but is widely accepted as the SNMPv2 standard.
SNMPv3 is a strong authentication mechanism, authorization with fine granularity for remote monitoring.
Traps supported: Cold Start, Authentication Failure.
The following MIBs are supported:
From RFC 1213 (MIB-II):
System group
Interfaces group
Address Translation group
