Planning:

F5	Big Big-IP
Intranet	192.168.100.0	255.255.255.0
External network	10.50.20.0	255.255.255.0
Virtual Server	Vs_web
Node_pool	Pool_web

Principle Realization Diagram:

================================================================

First, landing

Use one end of the network cable to connect the F5 's management port, and the other end to the PC's network port: The network card is set to 192.168.1.254

Use HTTPS login in chrome: https://192.168.1.254/

Factory Default User name: admin, Password: admin

Second, registered license

Click to view F5 Load Balancer activation license

Third, create a VLAN

"Create an intranet VLAN"

Click the "Create" button on the "Network→vlans" page:

Name:internal

TAG:100 (can be arbitrarily set, because my intranet is 100 network segment.) )

Port: 1.2 Move to UNTAG

"Create an Extranet VLAN"

Click on the "Create" button on the "Network→vlans" page to create the VLAN:

Name:extenal

TAG:100 (can be arbitrarily set, because my intranet is 100 network segment.) )

Port: 1.1 Move to UNTAG

Iv. creating IP for F5 itself

1, create their own intranet ip:192.168.100.7

Click the "Create" button on the "Network→self IPs" page:
IP Address column: 192.168.100.7 (fill in the intranet IP)
Netmask Fill in: 255.255.255.0 (fill in the intranet subnet mask)
VLAN Bar Selection: Internal
Port Lockdown Bar Selection: Allow default (default value)

2, create their own external network ip:10.50.20.2
Click the "Create" button on the "Network→self IPs" page:
IP Address column: 10.50.20.2 (fill out network IP)
Netmask Fill in: 255.255.255.0 (outside the net mask)
VLAN Bar Selection: External
Port Lockdown Bar Selection: Allow default (default value)

Iv. Creating a default gateway route

Vi. Creating server pools (pool)

Create Squid server pool: Pool_web
Click the "Create" button on the "Local traffic→pools" page:
Name field: Pool_web (please fill in an English name)
Load Balancing Method Bar selection: Round Robin (the load balancing method chosen here is polling, or other options available)
New Members column: First select new address, then add two Web server IP addresses 192.168.100.116,192.168.100.126 , and their port 80

Create Virtual server (Servers)

Create a Squid virtual server in "layer four" load Balancing mode: Vs_squid
Click the "Create" button on the "Local traffic→virtual Servers" page:
⑴, general properties under large categories:
①, Name field fill in: Vs_web (fill in an English name)
②, Destination column: Select Host, fill out the Web server's external network virtual IP, (virtual IP, referred to as VIP)
③, Service port column fill: 80
