About dae

dae is an open-source transparent proxy solution for Linux that performs traffic splitting inside the kernel using eBPF. When ipforward is enabled, direct traffic can bypass proxy application forwarding, which limits extra resource use for those connections.

It can split traffic by local process name, LAN MAC address, and invert match rules, select nodes by policy using separate TCP/UDP/IPv4/IPv6 latency tests, and handle DNS routing. It supports several proxy protocols and full-cone NAT for shadowsocks, trojan(-go) and socks5.

Key features

  • Kernel-level traffic splitting using eBPF
  • Direct traffic bypass when ipforward is enabled
  • Split local traffic by process name
  • Split LAN traffic by MAC address
  • Policy-based node switching using latency tests
  • Full-cone NAT for shadowsocks, trojan-go and socks5
Best for: Suited for Linux users who manage proxied and direct traffic with process, device, and policy rules.
Good for
  • Direct traffic bypasses user-space forwarding to reduce overhead
  • Granular splitting by process name, MAC address, and invert rules
  • Open-source code under AGPL-3.0 license
Watch out for
  • Requires Linux with ipforward enabled for direct traffic split
  • Co-hosted UDP servers need manual must_direct rule for server ports
  • Foreign DNS for domestic domains can cause long initial load times

dae FAQ

Is ipforward required for direct traffic handling?
Yes, Real Direct traffic split needs ipforward on.
What is needed when running a UDP server on the same public machine?
Add a l4proto(udp) && sport(your server ports) -> must_direct rule so outgoing UDP from that port stays direct.
Why can domestic websites load slowly on first visit?
Check DNS routing for domestic domains handled by foreign DNS, which can delay TLS handshakes.
Is something wrong or out of date?
