LSLB | Farms | Create

POSTED ON 3 May, 2022

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

HTTP profile: This profile works as a reverse proxy and it can manage HTTP and HTTPS protocols. A WebSocket is supported in ZEVENET v5.12 and it works in SNAT mode.

L4XNAT profile: This profile works as a router and it can manage any TCP, UDP, SCTP, SIP, FTP, TFTP, PPTP and SNMP. It works in DNAT, Stateless DNAT, SNAT, or DSR mode.

Create Farm LSLB

After clicking the Create Farm Action button, a new form to set up a new farm is shown.

A brief description of each form field

Name. A label that easily identifies an LSLB farm. This name is a unique identifier for the virtual service. Special characters like blank spaces, hyphens, or colons are not supported.

Virtual IP. The list will show all the IP addresses configured in the system network and are available for use by the farm virtual IP.

Virtual Port. This field holds a port number available on the system, where the Farm Profile will be listening. The port format is as follows:

  • 1. Only one port is available with a value between 1 and 65535 for HTTP profiles.
  • 2. A group of ports between 1 and 65535 for L4XNAT farms separated by a comma, for example, 25,110,143. Port ranges are defined by joining the 2 limit port numbers joined by the colon character: 2000:2100. All ports between the range separated by the colon will be included. You may use both columns and comma-separated ports as follows: 25,110,143,200:2100.

Profile. Defines the type of farm and load balancing topology for the new farm. You could choose one of the following profiles:

  • 1. HTTP. An advanced profile that has a layer 7 load-balancing proxy with special properties. Features like the HTTPS layer 7 load balancing combined with SSL offload acceleration are included in this profile. This profile is suitable for web services (web application servers included) and all applications based on HTTP and HTTPS protocols like WebDAV, RDP over HTTP, ICA over HTTP, WebSocket, etc. To configure this farm profile, a virtual IP address and a virtual TCP port will be required.
  • 2. L4xNAT. A high-performance load-balancing service at layer 4 that works on the kernel side (not userspace process based). L4xNAT profile handles multiple load-balancing methods like Source NAT, Stateless Destination NAT, Destination NAT, or Direct Server Return. The L4xNAT profile manages the following protocols: TCP, UDP, SIP, FTP, TFTP, SCTP, SIP, FTP, TFTP, AMANDA, H323, IRC, NETBIOS-NS, PPTP, SANE, and SNMP, and all protocols based on them. To configure this farm profile, a virtual IP address is needed. Later in the main farm configuration, you’ll set a protocol that handles a port or a range of ports (multiports).

Copy from farm. This option copies the configuration of a configured farm, modifying the previous Virtual IP and port.
Next step, update an LSLB farm.
