![]() Fortinet dynamic cloud security solutions protect workloads and business applications across on-premises data centers and cloud environments-with multilayer security for cloud-based applications. While AWS security covers its infrastructure, customers are responsible for protecting everything they build and store within it.įortinet accelerates the journey to AWS with purpose-built cloud security. Monitor VPN traffic status in IPSec Monitor TAB for further Troubleshooting.Many enterprises are turning to AWS to build new applications, extend internal data centers, and ultimately take advantage of the elasticity of the public cloud.Start following step-1 to step-22 to complete the VPN configuration in Firewall-2. Check Internal and External Interface IP address and Ports. ![]() **If requires, create a reverse clone policy for the connection to enable bi-direction action.įrom Step 1 to Step 37, VPN configuration has been completed for Firewall -1/Site-1. SSL Certificate is enabled to authenticate over SSL Inspection/ Its completely optionalģ6. Basic Anti-Virus has been enabled and Basic Application Control is enabledģ4. NAT is OFF and Protocol Options are Defaultģ3. Services/protocol – select all or you can select specific servuces like FTP/HTTP/HTTPSģ2. Destination address will be remote site Local LAN subnet 10.100.25.0/24ģ0. Source address which will be 80.25.0/24Ģ9. Traffic incoming from Inside Zone/Interface and Outgoing Interface will be Tunnel InterfaceĢ8. Assign name to the policy in IPV4 Policy TabĢ7. Assign Administrative distance 10 (static Routes)Ĭreate VPN- Policy for interesting traffic & allow ports according to requirementĢ6. Local LAN subnet going via Tunnel Interface To-FG-2Ģ5. Share Local LAN subnet which will communicate once VPN is establishedĬreate Static Route towards VPN Tunnel InterfaceĢ3. PFS (Enable Perfect Forward Secrecy)-Must be enabled at both peers end,Ģ0. Enable Anti-Replay Detection è Anti-replay is an IPSec security method at a packet level which helps to avoid intruder from capturing and modifying an ESP packet.ġ7. However, if the lifetime of key mismatched then it may lead to tunnel fluctuations. Key Lifetime – it defines when re-negotiation of tunnels is required. Diffie-Helliman is a key exchange protocol and creates a secure channel by exchanging public key /master key.ġ2. DH Group- Must be identical with remote peer (DH-5). Authentication methods verify the identity of peer user which means traffic is coming from correct user and there is no man-in-middle attack.ġ1. Authentication method – it must be identical with remote site. Encryption method provides end-to-end confidentiality to the VPN traffic.ġ0. Encryption Method, it must be identical with remote parties. Main mode is the suggested key-exchange method because it hides the identities of the peer sites during the key exchange.ĩ. Select IKE version to communicate over Phase I and Phase IIĨ. Enter Pre-shared Key, Pre-shared key is used to authenticate the integrity of both parties. Set address of remote gateway public Interface (10.30.1.20)Ħ. Name – Specify VPN Tunnel Name (Firewall-1)Ĥ. Select VPN Setup, set Template type Site to Siteģ. IPSec VPN Configuration Site-I Follow below steps to Create VPN Tunnel -> SITE-IĢ. IPsec parameters like encryption algorithm, authentication methods, Hash value, pre-shared keys must be identical to build a security association between two remote parties.įirewall -1, check internal interface IP addresses and External IP addresses Security Association are basis for building security functions into IPsec. IKE allows two remote parties involved in a transaction to set up Security Association. IKE uses port 500 and USP 4500 when crossing NAT device. IKE is used to authenticate both remote parties, exchange keys, negotiate the encryption and checksum that is used in VPN Tunnel. IPsec contains suits of protocols which includes IKE. IPsec supports Encryption, data Integrity, confidentiality. IPsec: It is a vendor neutral security protocol which is used to link two different networks over a secure tunnel. ![]()
