I am working on a project where an ACL will have a set of revolving IPs (not often, but from time to time a new node will be added/removed in a cluster that needs access into my network) and I have been provided with a URL to an XML document containing these IPs.
I can write a script that will allow me to check if the XML is updated and alert me to that, however, if this occurs at 2 am, there is little chance that I am aware until the morning comes. I am hoping there is a way to be more proactive, and allow the ASA to monitor this URL and update the object-group accordingly.
Any guidance would be appreciated.
Thanks,
Mark
