Firewall Load Balancing
Firewall load balancing distributes traffic across multiple firewalls, providing fault tolerance and increased throughput. Firewall load balancing protects your network by:
- Dividing the load between the firewalls, which eliminates a single point of failure and allows the network to scale.
- Increasing high availability.
Configuring a NetScaler appliance for firewall load balancing is similar to configuring load balancing, with the exception that the recommended service type is ANY, recommended monitor type is PING, and the load balancing virtual server mode is set to MAC.
You can set up firewall load balancing in a sandwich, an enterprise, or multiple-firewall environment configuration. The sandwich environment is used for load balancing traffic entering the network from outside and traffic leaving the network to the internet and involves configuring two NetScaler appliances, one on each side of a set of firewalls. You configure an enterprise environment for load balancing traffic leaving the network to the internet. The enterprise environment involves configuring a single NetScaler appliance between the internal network and the firewalls that provide access to the Internet. The multiple-firewall environment is used for load balance traffic coming from another firewall. Having firewall load balancing enabled on both the sides of NetScaler appliance improves the traffic flow in both the egress and ingress direction and ensures faster processing of the traffic. The multiple-firewall environment involves configuring a NetScaler appliance sandwiched between two firewalls.
Important: If you configure static routes on the NetScaler appliance for the destination IP address and enable L3 mode, the NetScaler appliance uses its routing table to route the traffic instead of sending the traffic to the load balancing vserver.
注意:对于FTP工作,额外的虚拟服务r or service should be configured on the NetScaler appliance with IP address and port as * and 21 respectively, and the service type specified as FTP. In this case, the NetScaler appliance manages the FTP protocol by accepting the FTP control connection, modifying the payload, and managing the data connection, all through the same firewall.
Firewall Load Balancing supports only some of the load balancing methods supported on the NetScaler appliance. Also, you can configure only a few types of persistence and monitors.
Firewall Load Balancing Methods
The following load balancing methods are supported for firewall load balancing.
- Least Connections
- Round Robin
- Least Packets
- B至少andwidth
- Source IP Hash
- Destination IP Hash
- Source IP Destination IP Hash
- Source IP Source Port hash
- Least Response Time Method (LRTM)
- Custom Load
Firewall Persistence
Only SOURCEIP, DESTIP, and SOURCEIPDESTIP based persistence are supported for firewall load balancing.
Firewall Server Monitoring
Only PING and transparent monitors are supported in firewall load balancing. You can bind a PING monitor (default) to the backend service that represents the firewall. If a firewall is configured not to respond to ping packets, you can configure transparent monitors to monitor hosts on the trusted side through individual firewalls.
