host can reach to the outside. If such restriction is desirable, then

additional firewall is needed.

Q. What can I do if the service that I want to load balance is not in the list?

R. WebMux as is already supports many different services. In the case if

your service is not in the list, you could use generic TCP and/or UDP to

set your farm. If that is still not good enough, you may contact us for

developing a special service aware module for you. In most cases,

there is a very reasonable fee to be charged.

Q Why secondary WebMux did not take over when I powered down

Primary WebMux?

R 1) Two WebMux not on the same version of firmware. Or 2) Secondary

WebMux monitors primary WebMux as well as few other things.

Before it takes over, it makes sure it can reach to the router LAN

gateway, as well as at least one server defined in any farm. If

secondary WebMux cannot reach to the front router LAN gateway, or it

cannot see any server in any farm, then it will consider the primary

disconnect or power down was done purposely by operator.

Q Why my FastIron Switch set to 100MB fix speed does not work with

WebMux?

R WebMux uses Intel network chipsets internally. Intel chipsets follows

all industrial standards and have good performance and reliability.

However, we did discovered some of the Foundry Networks switches

does not negotiate with Intel chipsets well. To make them work

together, one will need to set the switch to “auto negotiation” on speed,

instead of fixed 100. They will communicate each other at 100BT or

1000BT (Pro version only).
