In this example, neither the 192.168.211.0/24 nor the 192.168.105.0/24 networks can access the Internet directly.

The administrator configures Equalizer to provide outbound NAT service for these networks by using an IP

address on the 10.0.0.0/24 network when these internal networks need to talk to the Internet.

When configuring outbound NAT, the internal local network that is being configured for outbound NAT must use

the routing information for the external network which it is using NAT through. In the example above, the default

gateway for the 192.168.211.0/24 network will really be on the 10.0.0.0/24 network.

This is logical when you remember it this way: If Equalizer is sending a packet from the 192.168.211.0/24 network

to a host on the Internet, it has to be sent through the gateway of the external network, rather than the internal

network.

When Outbound NAT is enabled for a local network that contains attached destination networks, the destination

networks automatically inherit the same outbound NAT configuration.

Note - Outbound NAT is not supported for IPv6.

Network Permissions: Local networks configured in Equalizer use a

default deny

permission scheme. This means

that if an Administrator wants to route between two networks using Equalizer, they must explicitly enable

permissions between that pair of networks.

Note that permissions are not symmetrical: it is possible to configure a solution where one network can talk to

another but not vice-versa. For most configurations, permissions are necessary on both networks: if network 'A'

needs to route to network 'B', a permission must be added to 'A' for 'B' and another permission must be added to

'B' for 'A'.

Permissions are only necessary when using Equalizer to route packets. They are not required for Application

Traffic Management. That is, when an Equalizer cluster is paired with a server (by adding a server pool containing

that server to the cluster), Equalizer knows that any packets associated with a connection for that cluster should

be allowed on the server network.
