Just wondering how everyone is currently managing O365 IP’s on the ASA’s at the minute?
I am currently going through the list that MS provide and just copying out the hundreds of IP’s/Subnets and referring them to an object-group which then gets referenced in an ACL. I usually update the object-group with any new IP’s that MS release when I receive a notification via an RSS feed. This however is soon to cease so looking for a new way to keep the endless changing list of IP’s up to date, ideally automatically?
I have had a quick look at using REST which I can get a local client to pull a list of IP’s back to copy and paste again but was hoping that someone may have a better way of doing it than this? Have also looked at the FQDN route which is a no go with the ASA also.
Thanks,
Shaun
