Routing Traffic via Sophos XGS Firewall for Peered Workload VPC

Hello Team,

I've successfully configured the Sophos XGS in my security account and routed internal traffic via the Sophos LAN ENI instead of using a NAT gateway, which is functioning well. Now, I have another workload VPC in a separate account that is peered with the VPC in the security account. I want to route traffic from this workload VPC through the firewall instead of the NAT gateway.

Currently, traffic from the workload VPC is routed through the NAT gateway, and the VPC CIDR is routed via the peering connection. I've attempted to update the route table for the workload VPC to route all traffic through the peering connection, but it isn't working as expected.

Could you please advise on the next steps to ensure traffic from the workload VPC is routed through the firewall?

Thank you in advance.
