SSH Tunnel Manager

فارسی

A lightweight CLI tool to create and manage multiple SSH TUN (tun100+) tunnels with split-tunneling on Linux.
It generates per-tunnel configs under /etc/sshtunnel/, creates systemd units, and keeps routes/rules applied reliably.

✅ Tested on Ubuntu 24.04, 22.04

What this project does

• Client mode

  • Creates an SSH TUN interface (default: tun100, tun101, ...)
  • Assigns subnet automatically (10.99.100.0/30 … 10.99.255.0/30)
  • Applies split-tunnel policy routing (ip rule + separate routing table per tunnel)
  • Uses autossh + systemd for auto-reconnect
  • Ensures no tunnel conflicts (unique interface, subnet, routing table, and autossh monitor port)

• Server mode

  • Ensures SSHD supports tunneling (PermitTunnel yes)
  • Keeps server-side TUN interface configured
  • Enables NAT (MASQUERADE) for the tunnel subnet

---

Usage

Run:

sudo ./ssh_tunnel.sh

On first run, select Server or Client mode. After that, a menu is shown:

• Create new tunnel
• Manage tunnels (status, logs, edit split targets)
• Exit
