📝 Redirecting Egress Packets Through Cloudflare Tunnels via eBPF Program on Linux

not sure how to classify this, but chose documentation.

i use Cloudflare tunnels to expose my dev cluster to the Internet. packets come into through a tunnel, and then get redirected into an XDP load balancer on the physical NIC... which will either push the packet to another machine on the subnet or redirect it into the network namespace of a container.

my problem now is figuring out how i can use an eBPF program to redirect "response" packets back through either that same tunnel or another tunnel on another machine?

hoping this isn't impossible without switching to WARP connectors.
