Failover for AWS to Sophos S2S with Multiple Customer gateways

Hemanth Kurungat

Hi Team,

We have a client who has hosted some servers on AWS and has an XG firewall.

They have set up an Amazon VPC connected to a Sophos firewall via a single WAN interface. They possess two leased lines and require guidance on configuring a tunnel with both leased lines. Specifically, they need a failover for the AWS to Sophos site-to-site tunnel using their two leased lines.

Please let me know how we can configure this.

    Thank you for sharing the information. In the scenario where there are two ISPs in the Sophos firewall, are you suggesting to go for IPsec Site-to-Site (S2S) instead of Amazon VPC? If so, we Have to create two Customer Gateways (CGWs) and two Site-to-Site connections on AWS, and configure four Site-to-Site connections on the Sophos firewall. For knowledge purposes, how can this be achieved using RBVPN with static routing or BGP?
