Check Text (C-266998r1040760_chk)

Verify the AOS configuration with the following commands: show ip access-list vpnlogon show firewall-cp If PPTP or TCP 1723 are permitted, this is a finding.

Fix Text (F-70825r1040759_fix)

Configure AOS with the following commands: configure terminal cd /mm ip access-list session vpnlogon any any svc-pptp deny exit write memory cd /mynode firewall cp ipv4 deny any proto 6 ports 1723 1723 ipv6 deny any proto 6 ports 1723 1723 exit write memory
