Using an HTTP monitor without DNS lookup
Greetings.
I have run into an interesting problem... I have an internal F5 LTM configured with a VIP that serves internal clients only. To check on the pool members' health, I use the following GET command:
"GET http://appname.companyname.com/authentication.GetServerstatus/appname \r\n", where "appname.companyname.com" resolves to an internal IP address (10.x.x.x).
I am checking for an "OK" in the response, and things are working great.
Now the bad news: We need to expose the application to external users. So I build an external-facing VIP with a non-RFC1918 IP address, copy over the settings to our external-facing F5, and it mostly works - but the application is advertised externally with the same FQDN. When the external F5 looks up "appname.companyname.com" it goes via the management IP address, and I get the internal IP address.
Can I manually configure an IP address in the monitor? Or is there a smarter trick?
Thanks in advance!
