Opening up couchbase ports 8091 & 8092

For data access from certain other IPs, we have top open up 8091 & 8092.
But access entry for the external IP is not proving sufficient.
Has anyone faced this before? In one instance opening internal IP as well seemed to fix the issue.

Couchbase server is on the cloud as well on a different account.

thanks
