VPN Communities :- A VPNdomain is a collection ofinternal networks that use security Gateways to send and receive Its a collection of VPN tunnels and their attributes Network resources of different VPN Domains can securely communicate with each other through VPN tunnels that terminate at the security gateways in the VPN communities vpn communities are based on star and mesh topology. Two security gateways negotiate a link and create a VPN tunnel and each tunnel can contain more than one VPN connections One security gateways can maintain more than one VPN tunnel at the same time. The basis of site to site VPN is the encrypted VPN tunnel. Integrity :- uses industry- standard integrity assurance methodsĬheck point VPN solution uses these secure VPN protocols to manage encryption keys, and send encrypted packets IKE (internate key EXchange) is a standard key management protocol that is used to create the vpn tunnels ipsec is protocol that supports secure ip communication that are authenticated and encrypted on private or public networks Ipsec vpn software blade is used for encrypt and decrypt traffic to and from external networks and client use smart Dashboard to easily configure VPN connections between security gateways and remote devices the vpn tunnel guaranteesĪuthentication :- Uses standard authentication method like pre shared and certificate based create vpn tunnel both firewalls with secret key authentication and use vpn communities as star type and peer ip would be for dc-SG is 172.11.2.1 and for Branch_SG is 172.11.6.1 and interesting traffic would be same.Configure new security gateway with hostname of Branch-firewall and give a ip address of 172.11.5.1 and set a ip address of eth 1 interface is 172.11.6.1 and integration with SM.
