Standalone SoftEther VPN client written in Go. Connects to SoftEther VPN servers using the native protocol over TLS, with built-in DHCP, automatic reconnection, and route management.

Features

  • Native SoftEther protocol (TLS + HTTP handshake + TCP block framing)
  • Built-in DHCP client (raw Ethernet frame construction through the VPN tunnel)
  • Automatic reconnection with fresh DHCP on each reconnect
  • Host route to VPN server via existing default gateway (prevents routing loops)
  • Classless static routes (DHCP option 121/249, RFC 3442)
  • DNS configuration from DHCP lease (backup/restore of /etc/resolv.conf)
  • Hashed password (SHA-0) and plaintext password (RADIUS/external) authentication
  • Single static binary, Linux only

Contents

Requirements

  • Linux (uses /dev/net/tun for TAP devices)
  • CAP_NET_ADMIN or root (TAP device creation, route management)
  • ip command (iproute2) on $PATH
