Advanced Features
This screen allows you to change some advanced settings:
• NAT – NAT (Network Address Translation) is the technology which allows a number of LAN PCs
to share one (1) Internet IP address. These settings rarely need to be changed.
• Remote Access Configuration – This feature allows you to manage the Load Balancer 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 Load Balancer
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 WAN1 or WAN2 ports by selecting TCP/UDP
protocol.

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 Load Balancer needs 2
addresses, 1 for the LAN port, and 1 for the WAN port.)
• Generally, NAT is disabled only when you wish to use the Load Balancer
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
aren’t translated via WAN port.
