LSLB | Farms | Create Farm

Under this section you will be able to create LSLB farms, these farms can be configured in two different profiles:

  • HTTP profile: This profile works as a reverse proxy and it’s able to manage HTTP and HTTPS protocol. They work in SNAT mode.
  • L4XNAT profile: This profile works as a router and it is able to manage any TCP, UDP, SCTP, SIP, FTP and TFTP protocol. It works in DNAT or SNAT mode.

Create Farm LSLB

After selecting New Farm from the Actions button, a new panel to setup a new farm is shown.

Farm Name. It’s a farm naming and could be used to define a description of the virtual service to be provided. It is an unique identification for the virtual service. Special characters like blank spaces, hyphens or colons are not allowed.
Profile. Define the type of farm and load balancing topology for the new farm. You could choose one of the following profiles:

  • HTTP. It’s an advanced HTTP layer 7 load balancing with proxy special properties. It’s included in this profile features like HTTPS layer 7 load balancing combined with SSL offload acceleration. This profile is fits for web services (web application servers included) and all application protocols based on HTTP and HTTPS protocols like WebDav, RDP over HTTP, ICA over HTTP, etc. In order to configure this farm profile, a virtual IP address and a virtual TCP port will be required.
  • L4xNAT. It’s an high performance load balancing service at layer 4 that works in kernel side (not user space process based) which combines multiples of load balancing methods like Source NAT and Destination NAT. This profile could handle any kind of protocols like TCP, UDP, SCTP, SIP, FTP, TFTP, ICMP, etc, and all protocols based on them. In order to configure this farm profile, a virtual IP address will be required. Later, in the main farm configuration, it’s possible to set a certain protocol to handle, a port or a port range (multiport). It can also handle several protocol at once.

Interface. The list will show all the IP addresses configured in the system network configuration and available to be used for a farm virtual IP.

Port. This field has to be a port number available on the system, where the Farm profile will be listening in. The port format is as follows:

  • Only one port available between 1 and 65535 for HTTP profiles.
  • A group of ports between 1 and 65535 for L4XNAT farms separated by comma, for example: 25,110,143. Port ranges are defined joining the 2 limit port numbers joined by the colon character: 2000:2100, it will include all ports between the range, both numbers included. They can be used together as follows: 25,110,143,200:2100.

Next step, update a LSLB farm.
