• 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

Don't forget to Apply changes.

Setting up the local & remote group setup of a site-to-site connection

You have now successfully connected your device to GoodAccess.

Firewall rules

Make sure that your device allows incoming connections from your GoodAccess Gateway private subnet on the following ports:

• UDP 500

• UDP 4500

You may check the status of the connection in:

• GoodAccess - Control Panel > Clouds & Branches > Edit button > Test connection

• Cisco - VPN > Site-to-Site > Status > VPN Status

Step 4 (optional) - Enabling DPD
