The SIEM has a support phone home feature, but if you use ACLs, you'll need to add the support IPs in order for the McAfee team to get access. What is the block they use? I have two subnets, but I think there more. Here's what I have: 10.75.76.0/24 and 10.75.72.0/24. Are there others? Is there documentation calling these out?
