Supported Devices

Requirements

	Minimum	Comfortable
OpenWrt	18.06+	23.05+
RAM	128 MB	256 MB+
Storage	40 MB free	128 MB+
Kernel module	kmod-tun	kmod-tun

Note

At 128 MB RAM, enable zram swap before you connect. Without it, bringing up both WireGuard tunnels can OOM.

Architectures

Any OpenWrt device on one of these can install the package. 21 variants are built:

Tier 2 — stable Rust:

• aarch64_generic, aarch64_cortex-a53, aarch64_cortex-a53_neon-vfpv4, aarch64_cortex-a72
• x86_64
• i386_pentium4, i386_pentium-mmx
• arm_cortex-a5_vfpv4, arm_cortex-a7, arm_cortex-a7_neon-vfpv4, arm_cortex-a7_vfpv4
• arm_cortex-a8_vfpv3, arm_cortex-a9, arm_cortex-a9_neon, arm_cortex-a9_vfpv3-d16
• arm_cortex-a15_neon-vfpv4

Tier 3 — nightly Rust, experimental:

• mips_24kc, mips_siflower
• mipsel_24kc
• riscv64_riscv64
• arm_arm926ej-s

Buying for this

In rough order of how much it matters:

1. 256 MB+ RAM — the difference between working and OOM
2. aarch64 or x86_64 — Tier 2, stable toolchain, best throughput
3. OpenWrt 23.05+ — nftables/fw4, which is the better-tested firewall path here
4. Room in flash — the binaries are 18–36 MB installed, architecture dependent
