Virtual Server not working

Hello

I've set up a new virtual server and pointed it to an existing HTTPS virtual pool. However, when I browse to it I get 'The site can't be reached". We have another virtual server pointing to the same virtual pool and it works fine, the only difference is that the working one has a private IP and the non-working one has a public IP. For the vlan setup, should I only be enabling the vlan that the virtual server IP resides on? And should I enable SNAT or Automap? Any other ideas on what to check? If I look in the virtual server statistics I see connections being successfully made, it just doesn't seem to be reaching the nodes.

Thanks LB

You want to enable SNAT Automap if the default gateway of your back end server is NOT the BIG-IP, that will prevent asynchronous routing. The vlan should be enabled that the back end server is on.

Hope that helps! If it does please up-vote and select this answer, it would be greatly appreciated!

Hi Dylan

The vlan that the backend servers are on is not present on the F5.

Thanks LB

I agree with Dylan's answer.

In addition, by default a virtual server will listen on all VLANs. You can restrict which VLANs it listens on if you wish

For example for a private VIP you may want to listen just on the internal VLAN.

Also make sure you have a floating IP on each of the VLANs if you are using SNAT Auto Map.

You may want to check your vlan configuration. Can you post the output of a tcpdump to help diagnose the issues? Perhaps the device is having a routing issue. I have run into an issue before where requests come out the incorrect interface on the F5 if a floating IP is configured in the incorrect vlan.

If you have any more questions, I am sure I can help.
