Chapter 6: Administering Virtual Clusters
146 Equalizer Installation and Administration Guide
In the default outbound NAT configuration, the Network Address Translation (NAT) daemon maps internal server IP
addresses to Equalizer’s Default VLAN IP address (or the external interface IP address on the E250GX and legacy
‘si’ systems). You can also configure outbound NAT for individual servers, so server responses appear as if they
came from the cluster IP address, instead of Equalizer’s external interface IP address. The address used for outbound
NAT can be adjusted on a server by server basis, by clicking on the server in the left frame and opening the
Outbound NAT
tab. Outbound NAT must also be enabled in the global parameters, as shown below.
Enabling Outbound NAT
To enable outbound NAT:
1. Log into the Administrative Interface using a login that has add/del access for global parameters (see “Logging
In” on page 52).
2. Click on
Equalizer
(or the configured Failover Peer Name for this Equalizer) in the left frame, and open the
Networking
tab in the right frame.
3. Enable the check box next to
enable outbound NAT
.
4. Select the
commit
button.
Configuring Outbound NAT for a Server
Each server defined on Equalizer can have a specifically assigned outbound NAT address that overrides the default
(Equalizer’s external IP address). Note that outbound NAT must be enabled globally as described in the previous
section for server specific outbound NAT settings to take effect.
To configure an outbound NAT address for a server:
1. Log into the Administrative Interface using a login that has add/del access on the cluster to which the server
belongs (see “Logging In” on page 52).
2. Click on the name of the server in the left frame, and then open the
Outbound NAT
tab in the right frame.
3. Choose one of the following options:
4. Click
commit
to save your selection, which takes affect immeidately.
