NAT – NAT (Network Address Translation) is the technology which allows a number of LAN PCs to share one (1) Internet IP address.
Remote Access Configuration – This feature allows you to manage the XC-DPG602 via the Internet. You can restrict access to a specified IP address or address range.
External Filters Configuration – These settings determine whether or not the XC-DPG602 should respond to ICMP (ping) requests received from the WAN port.
Interface Binding – Use these to ensure that certain traffic is sent by a particular WAN port, and thereby a particular ISP account. These settings are only useful if using both WAN ports.
Protocol & Port Binding – This allows you binding WAN 1 or WAN 2 ports by selecting TCP/UDP protocol
Settings - Advanced Features
NAT Configuration
• NAT Routing – NAT (Network Address Translation) is the technology which allows one (1) WAN (Internet) IP address to be used by many LAN users.
- If you disable NAT, Internet access is only possible if all PCs are configured with valid Internet IP addresses. (The XC-DPG602 needs 2 addresses: 1 for the LAN port and 1 for the WAN port.)
- NAT is disabled only when you wish to use the XC-DPG602 as a Static Router.
• TCP Timeout – Enter the desired value to use on both WAN ports. The default is 300.
• UDP Timeout – Enter the desired value to use on both WAN ports. The default is 120.
• TCP Window Limit – Enter the desired value to use on both WAN ports. The default is 0 (no limit).
• TCP MSS Limit – Enter the required MSS (Maximum Segment Size) to use on both WAN ports. The default is 0 (no limit).
• Disable Port Translation – Enter the desired port range of all packets which are not translated via WAN port.
Remote Access Configuration
• Remote Upgrade – If enabled, you can u�
• Remote Web-based setup – If enabled, access to the Web-based interface is available via the Internet. If not enabled, access is only available to PCs on the LAN.
• Port – The port number used when connecting remotely. See below for details.
• Allowed IP range – Remote access is only available to the IP addresses entered here.
- Leaving these fields blank will allow access by all PCs.
- These addresses must be Internet IP addresses and not addresses on the local LAN.
- To specify a single address, enter it in both fields.
External Filters Configuration
These settings determine whether or not the XC-DPG602 should respond to ICMP (ping) requests received from the WAN port.
• Block Selected packet types – This acts as “master” switch. If checked, the selected packet types are blocked. Otherwise, they are accepted.
• Echo Request, Timestamp Request – Select the packet types you wish to block, using the checkboxes.
Dynamic Routing
• RIP v2 – This acts as “master” switch. If enabled, the selected WAN or LAN will run RIPv1/v2.
• LAN, WAN1, WAN2 – When enabled, any WAN or LAN can execute RIP function.
DNS Loopback
Some servers on a LAN and their domain names have already registered on public DNS. To avoid DNS loopback problem, enter the following fields.
• Domain Name – Enter the domain name specified by you for local host/server.
• Private IP – Enter the private IP address of your local host/server.
Interface Binding
SMTP (Simple Mail Transport Protocol) Binding (This applies only when using E-mail accounts from different ISPs on each port)
Some ISPs configure their E-mail Servers so they will not accept E-mail from IP addresses not allocated by themselves. If you are using accounts from different ISPs, sending E-mail over the wrong
port may result in non-acceptance of the mail. In this case, you can use these settings to correct the problem.
• Enable - When enabled, the port you specify below will be used for all outgoing SMTP traffic. If not enabled, either port will be used.
• WAN 1 / WAN 2 – Select the desired port.
Protocol & Port Binding
Use these settings if you wish to ensure user-defined traffic to be sent by a specific WAN port. This allows that user-defined traffic to be handled by a designated ISP account.
• Enable - Enable or disable each item as required.
• Source IP - IP address of source which packets are sent from.
• Destination IP – IP address of destination which packets are sent to.
• Subnet Mask – With subnet mask other than 255.255.255.255, you can make a IP sub-network as your destination.
• Protocol - Select the protocol used by the traffic you wish to configure.
• Port Range - Enter the beginning and end of the port range used by the traffic you wish to configure. If only a single port is used, enter the port number in both fields.
• WAN - Select the port you wish this traffic to use.
