A NAT Gateway for an Existing VCN with Its Route Table and a Reserved Address
A NAT gateway for an existing VCN with the private route table that sends subnets through it, because a gateway no table points at forwards nothing. The NAT address is ephemeral unless a reserved public IP is attached, and every allow-list that named it breaks on recreation; the ephemeral address is accepted by name. block_traffic, the kill switch, stays off and is exported.

Documentation
oci-nat-gateway
A NAT gateway for an existing VCN with the private route table that
sends subnets through it. Works with Terraform and OpenTofu
(>= 1.6), oci provider >= 8.0, < 9.0.
A gateway with no route rule forwards nothing; the private route table is created here and its ID exported for the subnets.
The NAT address is ephemeral unless a reserved public IP is passed; the ephemeral one is accepted by name.
block_traffic is a kill switch; off, and exported.
Verification
Static validation runs tofu fmt, init, validate, tflint and checkov.
This module has not yet had a live test, so it is published as statically
validated with its live test pending and does not carry the live-tested mark.

oci-remote-peering
A remote peering connection is half a link until the requestor connects to the acceptor, and a PEERED connection with no DRG route import and no VCN route rule passes nothing while reading as connected. Acceptor and requestor halves from one module, the peering status exported, and an output that lists the routes and security rules that live outside it and are the usual reason no packets cross.
oci-fastconnect
One virtual circuit is one cable that goes down for maintenance, and the SLA assumes two; BFD is off by default, leaving a failed link to BGP hold timers for up to ninety seconds; and a circuit without a gateway is PROVISIONED and reaches no VCN. BFD on, the DRG required, a redundant partner circuit declared or the single circuit accepted by name, and the redundancy metadata exported.
oci-local-peering
A local peering gateway with no peer stays NEW forever, and a PEERED pair with no route rule sending the other CIDR to the gateway passes nothing while reading as connected. Both gateways created and connected from one call, a route table with the rule to the peer created on each side for the subnets that should reach across, overlap refused, and an output that says it is not transitive.
oci-site-to-site-vpn
Every OCI IPSec tunnel is created with IKE version 1 unless told otherwise, and negotiates from a compatibility list that still accepts SHA-1, AES-128 and DH group 2 - so the weakest option a peer proposes is what it gets, and the tunnel shows UP. IKEv2 on both tunnels, explicit proposals for both phases with the weak ones refused by validation, BGP routing, and one configured tunnel only by name.
oci-drg-hub
Dynamic Routing Gateway with VCN attachments, custom DRG route tables, remote peering and IPSec/FastConnect attach points.
oci-vcn
Production VCN with public/private subnets, internet/NAT/service gateways, route tables, NSGs and IPv6 - the module every OCI tenancy starts with.
