Load Balancing & Networking
Destination Networks:
A specific remote network that has been configured by the Administrator as
connected to a local network of Equalizer. This means that if Equalizer needs to send packets to
this network, it should do so from an IP address on the local network and use the router of the
local network. For example:
In this configuration, 192.168.211.0/24 is a local network for Equalizer, configured by adding a
subnet to the configuration. 192.168.105.0/24 can be configured as a destination network of the
192.168.211.0/24 network. When adding a destination network, the administrator is configuring
several things:
l
In order to send packets from Equalizer to the destination network, Equalizer should use its
IP address on the local network. This how Equalizer selects an IP address to use when send-
ing a packet to the destination network. In order to do this, Equalizer actually sorts all of the
destination networks it knows about in most-specific to least-specific order. It then chooses
an appropriate IP address to use based on the first destination network to match.
l
Normally, Equalizer would not allow any packets that do not have a source IP address on
the local network. Adding the destination network means that Equalizer will now allow pack-
ets from this network to be routed with the same rules as packets from the local network.
l
Similarly, Equalizer will automatically add source routes for packets from the destination
network that match existing source routes for the local network.
l
If outbound NAT has been configured for the local network, analogous rules are added for
the destination network.
