Mid September McAfee upgraded their network connectivity for the update servers and for remote support access.
If you're having problems with getting updates to your appliances you may need to make some firewall rule changes
to correct the problem. McAfee has been sending out technology alerts, but I've found several users that have not
seen them or made these changes.
To allow McAfee support to access your appliances during a support case you need to open up "inbound" access
from:
161.69.15.4 on port 20022. This will allow McAfee to connect securely to the external management port.
To get updates to the software, AV Dat files etc... You need to make sure that
161.69.13.70 is allowed to connect
to your appliance as well. Most often if you are restricting access from certain IP addresses via your firewall, this will
be the case.
Additionally, if you want to clean up any firewall rules that may be outstanding. You can safely delete access from:
66.179.104.132
66.179.104.138
66.179.104.137
Here are the McAfee Knowledge based articles describing the changes:
