Rather than adding rule 7,

1/ Rather than adding rule 7, you can control the default action (traffic didnt match any of your rules) like this :

SnmpMibObject docsDevFilterIpDefault.0 Integer 1; /* discard */

2/ Your rules 2 and 5 are filtering in "both" directions, however you are matching on daddr / dmask. So that will work for eg outbound to 8.8.8.8, but not inbound from 8.8.8.8.
If you are trying to restrict access to allow only allow these 23.44.251.16 and 8.8.8.8 IPs, you probably need 4 x rules not 2, to match both the inbound and outbound traffic.
