The GL-SFT1200, designated as the Opal, utilizes a SiFlower SF19A28 System-on-Chip (SoC) housed within a compact chassis designed for portability. Performance metrics indicate peak wireless throughput of 300Mbps on the 2.4GHz band and 867Mbps on the 5GHz band. Aggregated data confirms that WireGuard VPN throughput is capped at approximately 65Mbps due to CPU processing overhead during encryption tasks. Physical dimensions allow for mobile operation via a 5V/3A USB-C power input.
Functional analysis lists the following operational features:
- Hardware Security: Physical toggle switch for VPN or Tor activation.
- Encryption Support: Native DNS over TLS via Cloudflare or NextDNS.
- Network Modes: Repeater, Bridge, and Access Point configurations.
Technical specifications confirm that the device operates on a proprietary version of OpenWrt. Thermal load monitoring suggests the unit reaches higher temperatures during sustained VPN encryption, requiring adequate ventilation. To ensure signal visibility in international regions, manual adjustment of 5GHz channels to non-DFS frequencies such as 36 or 44 may be required.
Users requiring higher encrypted throughput for 4K streaming should consider the Beryl AX which features a more powerful MediaTek processor. This unit is maintained in the vpn-routers database as a portable security gateway.
