An IPSec VPN for eZintegrations is a secure, encrypted tunnel that links your on-premise systems to eZintegrations Cloud. This connection allows eZintegrations and Goldfinch AI to access your enterprise systems safely, ensuring data confidentiality, integrity, and reliable transmission.

Key Benefits:

Direct, encrypted connection without third-party relays
Reduced latency and improved network performance
Secure access for enterprise applications, APIs, and databases

Benefits of Using IPSec VPN Setup for eZintegrations

Using an IPSec VPN Setup for eZintegrations ensures:

Data Security: All traffic is encrypted with AES-256-GCM and authenticated with SHA-256.
Reliable Connectivity: IKEv2 provides stable key negotiation and tunnel recovery.
Compliance: Securely meets regulatory and corporate network policies.
Scalability: Handles multiple endpoints, applications, and large-scale data flows.

Step-by-Step Configuration of IPSec VPN Setup for eZintegrations

1. Pre-Requisites

On-prem firewall/VPN gateway (Cisco, Palo Alto, FortiGate, Oracle VPN CPE)
Public static IP for on-prem WAN interface
Network CIDRs for systems connecting to eZintegrations Cloud
Technical contact for configuration and maintenance

2. Gather Network & Device Details

List application servers, databases, file shares, and APIs to connect
Identify IP addresses, ports, and protocols required (e.g., HTTPS 443, SFTP 22)

3. Complete IPSec VPN Setup Form

Fill the IPSec_Setup_Form.xlsx with IPs, CIDRs, device info, and go-live date

4. Exchange Security Parameters

Choose Pre-Shared Key (PSK) or Certificate-based authentication
Bizdata provides remote gateway IP and recommended IKE/IPSec parameters
Share your public IP and identifiers via an encrypted channel

Recommended IPSec Settings:

IKE Version: IKEv2
Encryption: AES-256-GCM
Hash: SHA-256
Diffie-Hellman Group: 14 (or higher if required)
Lifetime: 28800 sec (Phase 1 & 2)
Mode: Tunnel Mode
PFS: Enable

5. Configure Oracle Cloud Side

Create VCN & attach DRG for IPSec connections
Create IPSec connection linking DRG to Customer-Premise Equipment (CPE)
Provide Oracle public endpoint & PSK to on-prem team

6. Configure On-Prem Firewall

Configure IPSec tunnel using remote peer, PSK/certificates, encryption & hashing
Apply NAT rules and ensure no port conflicts

7. Routing & Access Controls

Add static routes or configure BGP to route traffic over the IPSec tunnel
Update firewall rules and Oracle security lists to allow traffic from internal networks

8. Test Connectivity

Ping, traceroute, or telnet to Bizdata endpoints
Verify tunnel status and Security Associations (SAs)

9. Monitoring & Alerting

Monitor IPSec tunnel via Oracle Cloud Console (OCI)
Set alerts for downtime, latency, or packet drops

Keys and Credentials — What to Exchange

Public IPs of gateways
PSK or Certificate public keys
Local & remote identifiers
Allowed CIDRs

Purpose: Authenticate endpoints, ensure confidentiality, and prevent unauthorized access.

Troubleshooting IPSec VPN for eZintegrations

Verify IPs and PSK match
Confirm encryption & hashing align
Check for overlapping subnets or NAT issues
Validate routing entries and firewall rules

FAQ

1. What is an IPSec VPN for eZintegrations?
