The WebMux™ Model 480S, 580SG, and 680PG User Guide – Version 7.0.x

Server gateway IP address:

The WebMux™ appears to all the servers in the farms as a gateway or router.

This is the IP address for the WebMux™ acting as a router for the servers. This

address should be the gateway IP address in the web (or other) servers. It is

highly recommend adding it to the /etc/hosts file on your servers. Only apply for

the NAT mode (or for Out-of-Path mode that requires the WebMux™ to do the

SSL termation or Layer 7 load balancing. Normally, it this is optional for Out-of-

Path mode).

PLEASE NOTE: For first time setup, it is very important to set up this address

and the Server Farm network mask (below) first. Also when setting up the

servers, you may be asked to fill in the default gateway IP address for the server.

Use this IP address to setup all the servers under it. The WebMux™ will not

function properly if this IP address is not set correctly for both WebMux™ and the

servers.

WebMux™ http control port:

Since the WebMux™ is load balancing incoming HTTP traffic, the HTTP port for

the management console must be set to a different port. By default, the port is

24. You can change the port, if so desired. The font push buttons can also

change this.

WebMux™ https control port:

Since the WebMux™ is load balancing incoming HTTPS traffic, the HTTPS port

for the management console must be set to a different port. By default, the port

is 35. You can change the port, if so desired. The front push buttons can also

change this.

WebMux™ diagnostic ports:

The WebMux™ allows diagnostic sessions from remote access for factory

technical support or trained network engineers through ssh or telnet. Access is

also subject to the restriction of the “Allowed-Host” setting earlier. “superuser”

can login with its password using “ssh” to run certain diagnostic tools (help shows

the commands, how to use these commands are not supported). When this entry

is blank, any diagnostic access is denied. This entry should remain blank under

normal operations. Default port numbers are 77 / 87. The first port is ssh and

second is telnet. If only one port specified, only ssh login is possible. You will

need to notify us the port numbers before obtaining support from us.

Connection warning threshold:

The WebMux™ monitors the number of connections established. When the

number of connections is greater than the value entered, the WebMux™ will

page the designated numbers. For example, if a DoS attack is occurring, the

number of connections to the site would be extremely high. Assuming they
