Network Setup
- The WAN configuration allows you to setup the basic connectivity between the RX3141 and your ISP. Please obtain information regarding ISP connection type & related information before proceeding with the configuration.
- Select the WAN port connection type from the connection mode drop-down list. Four types of WAN connection mode are supported: Static, DHCP, PPPoE (multi-session), PPPoE unnumbered.
- For PPPoE multi-session settings, you can use 'Route to' option in the OUTBOUND ACL configuration page to control traffic uplink.
- For PPPoE unnumbered settings, please set the LAN IP address and netmask to those provided by your ISP.
Administration
- WAN MAC option lets you change the WAN interface MAC address.
- UPnP service: Enable this option to use MSN Messenger video/audio/file transfer services.
- Administration from WAN interface: Enable this option to allow you to manage this device via the WAN interface. Port is 8080.
Firewall
- DoS Attacks Filter Configuration
Use this option to configure DoS parameters. By default, your network is protected against the attacks listed in the DoS Attack Protection List table. You may check or uncheck individual option to enable or disable protection against specific type of attack.
- Log Port Probing
Connection attempt to closed ports of this system will be logged if this option is enabled. This can be evidenced by the port scans. - Stealth Mode
If enabled, system will not respond to the initiator when the remote peer initiates connection to system's TCP or UDP closed ports.
- SYN/ICMP/UDP flooding
These attacks involve sending lots of TCP SYN/ICMP/UDP packets to a host in a very short time. This may slow down the victim's response time or crash the victim. System will not drop the flooding packets because doing so may affect the normal packets.
Outbound/Inbound/Self-access
- Outbound
Traffic from LAN to WAN is regarded as outbound traffic.
- Inbound
Traffic from WAN to LAN is regarded as inbound traffic.
- Self-Access
Traffic destined to or originated from this device is regarded as self-access traffic.
Virtual Server
- Virtual Server is used to allow Internet users access to the LAN services. Skip this, if you don't intend to provide LAN services to Internet users.
- Note that you need to configure this for certain applications like MS NetMeeting that requires multiple connections and also requires remote peer to initiate connection into your LAN.
Special Application
- Special Applications let you automatically forward certain TCP and UDP connections from the Internet into your LAN when computers in your LAN initiated access to the specified Internet services. This is done by defining trigger ports and incoming ports. Trigger ports are initially issued by the application. When the trigger port is detected, the inbound packets to the corresponding incoming ports are redirected into your LAN.
- Note that you need to configure this for certain applications like MS NetMeeting that requires multiple connections and also requires remote peer to initiate connection into your LAN.
