The WebMux Pro and Model WM108E User Guide – Version 5. 8 Rev15

• Built-in Firewall Protections. Stop possible hacker intrusion into your

network from Internet. All IP addresses and ports are blocked except the

farm IP address. Built-in functions will detect any possible denial of service

attack and make your services always available. (Note: this function only

works in NAT mode with “Forwarding Deny”, see setup for details).

• In-Path or Out-of-Path Load Balancing. In normal setup, the WebMux

can be configured In-Path, to act as firewall in addition to the load

balancer and health checker. However, if outbound traffic is much larger

than inbound traffic and you already have a firewall in place, or change of

IP address causes problem, consider using Out-of-Path configuration.

Out-of-Path load balancing is also called direct routing, or one leg

operation.

• Informs you of the status of your network. It provides phone pager and

email notification so that the network administrator can be paged or

emailed whenever a server or WebMux goes down, and when it returns

online. This feature could reduce server room night shift operator costs, or

timely repair should the server goes down unexpectedly.
