Sandwich Environment
A NetScaler deployment in a sandwich mode can load balance network traffic through firewalls in both directions: ingress (traffic entering the network from the outside, such as the internet) and egress (traffic leaving the network to the internet).
In this setup, a NetScaler is located on each side of a set of firewalls. The NetScaler placed between the firewalls and the Internet, called the external NetScaler that handles ingress traffic selects the best firewall, based on the configured method. The NetScaler between the firewalls and the private network, called the internal NetScaler tracks the firewall from which the initial packet for a session is received. It then makes sure that all subsequent packets for that session are sent to the same firewall.
The internal NetScaler can be configured as a regular traffic manager to load balance traffic across the private network servers. This configuration also allows traffic originating from the private network (egress) to be load balanced across the firewalls.
The following diagram shows the sandwich firewall load balancing environment.
Figure 1. Firewall Load Balancing (Sandwich)
The service type ANY configures the NetScaler to accept all traffic.
To avail benefits related to HTTP and TCP, configure the service and virtual server with type HTTP or TCP. For FTP to work, configure the service with type FTP.
Configuring the External NetScaler in a Sandwich Environment
Perform the following tasks to configure the external NetScaler in a sandwich environment
- Enable the load balancing feature.
- Configure a wildcard service for each firewall.
- Configure a monitor for each wildcard service.
- Configure a wildcard virtual server for traffic coming from the Internet.
- Configure the virtual server in MAC rewrite mode.
- Bind services to the wildcard virtual server.
- Save and Verify the Configuration.
Enable the load balancing feature
To enable load balancing by using the command line interface
At the command prompt, type the following command to enable load balancing and verify the configuration:
enable ns feature LB
show ns feature
<!--NeedCopy-->
Example:
> enable ns feature LoadBalancing
Done
> show ns feature
Feature Acronym Status
------- ------- ------
1) Web Logging WL OFF
2) Surge Protection SP ON
3) Load Balancing LB ON
.
.
.
24) NetScaler Push push OFF
Done
<!--NeedCopy-->
To enable load balancing by using the configuration utility
Navigate to System > Settings and, in Configure Basic Features, select Load Balancing.
Configure a wildcard service for each firewall
To configure a wildcard service for each firewall by using the command line interface
At the command prompt, type:
add service <name> <serverName> ANY *
<!--NeedCopy-->
Example:
add service Service-HTTP-1 10.102.29.5 ANY *
<!--NeedCopy-->
To configure a wildcard service for each firewall by using the configuration utility
Navigate to Traffic Management > Load Balancing > Services and add a service. Specify ANY in the Protocol field and * in the Port field.
Configure a monitor for each wildcard service
A PING monitor is bound by default to the service. You need to configure a transparent monitor to monitor hosts on the trusted side through individual firewalls. You can then bind the transparent monitor to services. The default PING monitor monitors the connectivity only between the NetScaler appliance and the upstream device. The transparent monitor monitors all the devices existing in the path from the appliance to the device that owns the destination IP address specified in the monitor. If a transparent monitor is not configured and the status of the firewall is UP but one of the next hop devices from that firewall is down, the appliance includes the firewall while performing load balancing and forwards the packet to the firewall. However, the packet is not delivered to the final destination because one of the next hop devices is down. By binding a transparent monitor, if any of the devices (including the firewall) are down, the service is marked as DOWN and the firewall is not included when the appliance performs firewall load balancing.
Binding a transparent monitor overrides the PING monitor. To configure a PING monitor in addition to a transparent monitor, after you create and bind a transparent monitor, you need to bind a PING monitor to the service.
To configure a transparent monitor by using the command line interface
At the command prompt, type the following commands to configure a transparent monitor and verify the configuration:
add lb monitor <monitorName> <type> [-destIP <ip_addr|ipv6_addr|*>] [-transparent (YES | NO )]
bind lb monitor <monitorName> <serviceName>
<!--NeedCopy-->
Example:
add monitor monitor-HTTP-1 HTTP -destip 10.10.10.11 -transparent YES
bind monitor monitor-HTTP-1 fw-svc1
To bind a PING monitor, type the following command:
bind monitor PING fw-svc1
<!--NeedCopy-->
To create and bind a transparent monitor by using the configuration utility
Navigate to Traffic Management > Load Balancing > Monitors, and then create and bind a transparent monitor.
Configure a wildcard virtual server for traffic coming from the Internet
To configure a wildcard virtual server for traffic coming from the Internet by using the command line interface
At the command prompt, type:
add lb vserver <name> ANY * *
<!--NeedCopy-->
Example:

<!--NeedCopy-->
To configure a wildcard virtual server for traffic coming from the Internet by using the configuration utility

To configure the virtual server in MAC rewrite mode by using the command line interface
At the command prompt, type:
set lb vserver <name>@ -m <RedirectionMode>
<!--NeedCopy-->
Example:
set lb vserver Vserver-LB-1 -m MAC
<!--NeedCopy-->
To configure the virtual server in MAC rewrite mode by using the configuration utility
- Navigate to Traffic Management > Load Balancing > Virtual Servers, and select the virtual server for which you want to configure the redirection mode (for example, Vserver-LB-1).
- Edit the Basic Settings section, and click more.
- From the Redirection Mode drop-down list, select MAC Based.
Bind services to the wildcard virtual server
To bind a service to the wildcard virtual server by using the command line interface
At the command prompt, type:
bind lb vserver <name> <serviceName>

- Click in the Services section and select a service to bind.
Save and Verify the Configuration
When you’ve finished the configuration tasks, be sure to save the configuration. Ensure that the settings are correct.
To save and verify the configuration by using the command line interface

Monitoring a Firewall Load Balancing Set up in a Sandwich Environment
After the configuration is up and running, you should view the statistics for each service and virtual server to check for possible problems.
Viewing the Statistics of a Virtual Server
To evaluate the performance of virtual servers or to troubleshoot problems, you can display details of the virtual servers configured on the NetScaler appliance. You can display a summary of statistics for all the virtual servers, or you can specify the name of a virtual server to display the statistics only for that virtual server. You can display the following details:
- Name
- IP address
- Port
- Protocol
- State of the virtual server
- Rate of requests received
- Rate of hits
