F5 BIG IP LTM virtual server

Hello,

Check below points,

1. As Virtual Server status is showing Available that means the backend web server pool is up. Now first check basic connectivity to VS first from client. Try by telnetting VS IP on port 80 from client machine. This will confirm if client request reaching F5 VS or not.
2. Also why there is no http profile configured on VS. To act F5 as normal reverse proxy, you should have http profile configured on VS. Please configure default 'http' profile on it.
3. Check SNAT settings. If your backend web-server's gateway is not F5 (it is on switch etc) then you need to enable SNAT settings. Otherwise it will create Asymmetric Routing issues.
4. You can even check hits to backend pool members. Check if requests are getting forwarded to backend pool members when client tries to connect VS. This can be seen under statistics.

If still there are issues, please put full snap of VS configuration.

check snat settings.

this is my configuration

can you provide a sample photo for what you explained before?

Hi rifki, you configuration seems right prima facie and answer for you question "how do you connect the client to the virtual server?" is by typing in internet browser "http://192.168.42.254" and also cross-check via command "telnet 192.168.42.254 80" for success by client machine.

I have typed in http://192.168.42.254 but still can't

how to check telnet 192.168.42.254?

As you have VS using private IP, you need to do telnet test from the system from where VS IP will be reachable. e.g LAN system. Just put below command from cmd,

​

telnet 192.168.42.254 80

​

And see if you're able telnet it. Also have you checked the other settings that i've mentioned in my earlier comments.
