to combine. When too large a mask applied, it will defeat the load balancing

function of WebMux.

ICMP Packet input policy:

• Accept: The WebMux will allow all ICMP packets to travel through the

WebMux. For CLI arp commands working properly, this must be accept.

• Deny: The WebMux will NOT allow any ICMP packets to travel through

the WebMux.

Note: During installation, having the ability to PING the other hosts on the networks is typically

useful. When the installation is complete, setting the “ICMP packet policy” to DENY, is

recommended as a security precaution.

Forward Policy:

• Accept: The WebMux will route IP packets both directions. WebMux will

not act as a firewall in this mode.

• Deny: The WebMux will NOT allow any incoming IP packet traveling

through the WebMux, except IP packets in farm IP/port. This is the default

setting.

Front Router Connection Verification:

It can be “none”, “ARP”, “TCP Connection”, or “ping”. Depending on the front

end router, this can be changed. For example, most Cisco routers will talk to

WebMux through ARP and TCP Connection; however, most Cisco DSL modems

will only talk to WebMux through Ping. The change to this verification method

will take effect after WebMux being rebooted.

Front Router Connection Verification IP Address:

It can be the router in front of the WebMux, or a router in your ISP’s WAN. It is

recommended to have the router IP address as the verification IP address.

However, it can be any address that is reachable on your Internet side.

Persistence Timeout:

WebMux will keep track the browser connections if the persistent farm is defined

and accessed. Within the timeout time period, WebMux will send any request

from the browser IP address to the same server. Our survey shows 5-6 minutes

is the best value for most cases. The larger the persistence timeout value, the

less chance user connection get lost. However, by keeping a lot of connections

in the WebMux memory, the maximum number of concurrent connections will

drop.

Outbound Connection Timeout:

WebMux keeps track the outbound connections. This outbound proxy function

provides communication tunnels for servers behind it to talk to other computers

on the Internet side. This type of connection is different from the connections
