AIX7-00-002063 - AIX must be configured with a default gateway for IPv4 if the system uses IPv4, unless the system is a router.

Information

If a system has no default gateway defined, the system is at increased risk of man-in-the-middle, monitoring, and Denial of Service attacks.

Solution

Set a default gateway for IPv4 using:
# route add 0 <ip address of gateway>
