user is not able to access a server using a VIP

If the VIP is showing as down, then the health monitor is failing.

 

What kind of application is it? What is the health monitor assigned to the pool?

 

Hi,

 

your problem is clearly related to monitoring.

 

So first of remove monitoring from POOl / Pool memember. you VS will be blue which means he is not monitored.

 

Then if is a web service check the following point:

 

• Snat Automap is activated.
• HTTP Profile is set (If a web service).
• Client SSL is activated (if you want to set up offload ssl).
• SSL server is activate if your backend is in TLS...

Then to build your monitor you have to use Curl in order to check response from your backend. Use CLI then use the following command:

 

Backend in https:

 

curl -i -k https://1.1.1.1/uri --header "Host: app.mydomain.com"

 

Backend in http:

 

curl -i http://1.1.1.1/uri --header "Host: app.mydomain.com"

 

Check the response in order to built your monitor...

 

let me know if you need more details.

 

regards.
