Check Contents

Review the configuration of each HP FlexFabric Switch interface connecting to an Alternate Gateway.

Verify that the ACL configured to block unauthorized networks are configured on the interface.

Verify each permit statement of the ingress filter only permits packets with destination addresses of the site's NIPRNet address space or a destination address belonging to the address block assigned by the Alternate Gateway network service provider.

If the ACL is not configured to only permit packets with destination addresses within the sites address space, this is a finding.
