lab LTM - networks not hitting default gateway

Hi Sam, I think I'm following your logic. Maybe I can explain this better. So from the top I have 2 servers that are the targets. Addresses are 10.100.192.71 and 72.

My goal is to route from an endpoint through the f5 to an IP that forwards to either of 10.100.192.71 or 72 depending on the health monitor GURL.

So I have created the pool members and added them to a virtual server with address 10.100.192.76. I think this far is ok.

I have added an external network on 10.100.5.176- this is my endpoints network. that I want to be able to get to 10.100.192.71 and 72. I have created a vlan and self ip for this.

I have also created an internal network on 10. 100.26.11- not sure if I really need this as the main concept it to get the external network devices to talk to 10.100.192.76. One question here is do I need to add the /24 network or adding a host acceptable

After I have set all that up I'm not able to get to the 2 servers in question from a device on the external network (its actually within the network just on a different vlan on esxi)

When troubleshooting I'm not able to hit the .1 addresses of the external network from the F5 as there is no known route. I'm new to the setup of the F5 and I think I may be over complicating it.

I'm not referencing DNS so I don't know is OCSP would come into this?

kind regards,

Graeme
