• IKE Lifetime (Phase 1) - 8 hours (28800 seconds)

• Tunnel Lifetime (Phase 2) - 1 hour (3600 seconds)

• Dead Peer Detection Delay - 30 seconds

• Encryption (Phase 1) - aes256

• Encryption (Phase 2) - aes256

• Integrity (Phase 1) - sha256

• Integrity (Phase 2) - sha256

• Diffie-Hellman Groups (Phase 1) - 16 - modp4096

• Diffie-Hellman Groups (Phase 2) - 16 - modp4096

Step 2 - Creating a new site-to-site connection

Must match configuration from GoodAccess (Step 1).

Switch to Manual, and set the configuration as follows:

• Key Exchange Version - IKEv2

• IKE (Phase 1)

  • Encryption - AES-256

  • Hash - SHA256

  • DH Group - 16

  • Lifetime - 28800

• ESP (Phase 2)

  • Encryption - AES-256

  • Hash - SHA256

  • DH Group - 16
