Nacl Quota issue

You can increase the Network ACL rules quota through AWS Support. By default, each Network ACL has a quota of 20 rules per direction (20 inbound and 20 outbound rules).

In your case with 19 inbound and 7 outbound rules, you're hitting the limit on the inbound side. This quota is adjustable and can be increased up to a maximum of 40 inbound rules and 40 outbound rules (for a total of 80 rules). However, be aware that increasing this quota beyond the default may impact network performance.

To request a quota increase, you'll need to submit a request through AWS Support. When making your request, specify that you need to increase the "Rules per network ACL" quota and indicate the new limit you require based on your needs.

Keep in mind that there are also quotas for the number of Network ACLs per VPC (default is 200), which is separate from the rules per Network ACL quota.
