GTM configuration

Ok worked it out for the public addresses. So step 6, 7 & 8 should be as follows:

 

6 - create server with public address (this is the address GTM should resolve in the DNS query). Add a virtual server and load balancing method to server.

 

7 - create a pool that adds the server in step 6 as a member.

 

 

8 - create wide IP of FQDN, such as sftp.sub.domainaus.com.au and use pool in step 7.

 

 

What I have found is that my monitors are not getting a positive response back from the servers in step 6. I have set my load balance as Global Availability and no alternate or fallback to get the DNS query against GTM to still have the correct response. Working on my monitors, but what are the best ones to use when the backend LTM virtual server is listening on a public address and not a NAT address?
