Basic F5 LTM HTTP Load Balance Configuration (With Firewall)

The BIG-IP® local traffic management system is specifically designed to manage your local network traffic. Local traffic management refers to the process of managing network traffic that comes into or goes out of a local area network (LAN), including an intranet.

A commonly-used feature of the BIG-IP system is its ability to intercept and redirect incoming network traffic, for the purpose of intelligently tuning the load on network servers. However, tuning server load is not the only type of local traffic management. The BIG-IP system includes a variety of features that perform functions such as inspecting and transforming header and content data, managing SSL certificate-based authentication, and compressing HTTP responses. In so doing, the BIG-IP system not only directs traffic to the appropriate server resource, but also enhances network security and frees up server resources by performing tasks that web servers typically perform.

F5 LTM / GTM Best Practice Deisgn With Routers and Firewalls

There are always questions how to place your F5 GTM and LTM. Different situation has different solution design. Here are some simple examples when I used to explain the location of LTM/GTM.

1. LTM only (Without GTM)

The devices order should look like this: 

Internet ---> Router ---> Firewall ---> F5 LTM  ---> DMZ Servers

or

Firewall Sandwiches:
Internet ---> Router --->F5 LTM  --> Firewall ---> F5 LTM ---> DMZ Servers

F5 (Tips and Tricks)

1. Restoring the BIG-IP configuration to the factory default setting

Impact of procedure: This procedure removes all BIG-IP local traffic objects, network configuration, and BIG-IP module data. Admin and Root password will be reset to default. Your MGMT interface ip address will be kept.

1.1 Log in to the Traffic Management Shell (tmsh) by typing the following command:
tmsh

1.2 To restore the configuration to the factory default setting, type the following command:
load sys config default

1.3 You are prompted with the following confirmation:
Reset the system configuration to factory defaults? (y/n)

To confirm that you want to restore factory default values, press the following key:
y

1.4 Save the change by typing the following command:
save sys config partitions all

1.5 Reboot the BIG-IP device
reboot


2. Upgrade F5 TMOS

2.1 Download the ISO File from F5 Downloads site.
File name is BIGIP-12.1.2.0.0.249.iso. Make shre verify file's MD5 value

1. Download 

Download F5 BIG-IP v11.x / Virtual Edition 11.3.x from one of three following F5 links:

a. ftp://[email protected]/downloads/wbqstXPthWwYVGZnWNOfZd3e3M-F0IrRom89/BIGIP-11.3.0.2806.0-scsi.ova

b. http://downloads02.f5.com/esd/download.sv?loc=downloads02.f5.com/downloads/wbqstXPthWwYVGZnWNOfZd3e3M-F0IrRom89/BIGIP-11.3.0.2806.0-scsi.ova

c. https://downloads02.f5.com/esd/download.sv?loc=downloads02.f5.com/downloads/wbqstXPthWwYVGZnWNOfZd3e3M-F0IrRom89/BIGIP-11.3.0.2806.0-scsi.ova

2. use ovftool.exe convert ovf file to vmx file
syntax is : ovftool "c:\f5\bigip-11.3.0.ovf" "c:\vm\bigip-11.3.0.vmx"
there are two files generated after conversion finished, which is  BIGIP-11.3.0.2806.0-scsi.vmx and BIGIP-11.3.0.2806.0-scsi-disk1.vmdk

3. Open it from Vmware Workstation

4. Log into Big-IP LTM with root user.
Default password is default. Eth1.mgmt is pre-configured ip address 192.168.1.245/24.

If bridged vm's network adapter to right local network card, browser should be able to open https://192.168.1.245. Root user can not be used to log into GUI. But admin/admin account is able to do that.

after log into web GUI, the first step will be to activate device with proper license.

5. License
On F5 website, you could get trail key for 10.1 which has some limitation to the VE. For other higher version, partner will be best place to get the license key . Or order one LAB license from F5 to set up lab to play.

After licensed VE, the GUI will show all navigation menu on the left.
