this screen allows you to change some advanced settings:
1 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.
2 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.
3 external filters configuration ?these settings determine whether or not the load balancer should respond to icmp (ping) requests received from the wan port.
4 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.

using remote web-based setup
to connect to the load balancer from a remote pc via the internet:
1. ensure that both your pc and the load balancer are connected to the internet.
2. start your web browser.
3. in the "address" bar, enter "http://" followed by the internet ip address of the load balancer. if the port number is not 80, the port number is also required. (after the ip address, enter ":" followed by the port number.) e.g.
http://123.123.123.123:8080
(1)this example assumes the wan ip address is 123.123.123.123, and the port number is 8080.
(2)if using the dynamic dns feature, you can connect using the domain name allocated to you. e.g.
http://my_domain_name.dyndns.org:8080
