Fix Recommendation

This requirement is not applicable for the DODIN Backbone.

Configure the router to allow only incoming communications from authorized sources to be routed to authorized destinations.

ICX(config)#ip access ext FILTER_PERIMETER
ICX(config-ext-ipacl-FILTER_PERIMETER)#permit tcp any any established
ICX(config-ext-ipacl-FILTER_PERIMETER)#permit udp host x.12.1.9 host x.12.1.21 eq ntp
...
ICX(config-ext-ipacl-FILTER_PERIMETER)#deny ip any any log

ICX(config)#interface ethernet x/x/x
ICX(config-if-e10000-x/x/x)#ip access-group FILTER_PERIMETER in logging enable

Check Contents

This requirement is not applicable for the DODIN Backbone.

Review the router configuration to determine if the router allows only incoming communications from authorized sources to be routed to authorized destinations.

The example below allows inbound NTP from server x.1.12.9 only to host x.12.1.21:

ip access-list extended FILTER_PERIMETER
sequence 10 permit tcp any any established
sequence 20 permit udp host x.12.1.9 host x.12.1.21 eq ntp
...
sequence 30 deny ip any any log
!
interface ethernet x/x/x
ip access-group FILTER_PERIMETER in logging enable

If the router does not restrict incoming communications to allow only authorized sources and destinations, this is a finding.
