VPN Tunnel Manager - User Guide
What This Script Does:
This script helps you manage your VPN tunnels without needing to remember complex OpenSwan commands.
Basic Usage:
Show Help and List Tunnels:
sudo sh ./vpn-manager.sh
Shows this help guide and lists all your VPN tunnels with their current status.
Check Status of All Tunnels:
sudo sh ./vpn-manager.sh status
Check Status of Specific Tunnel:
sudo sh ./vpn-manager.sh status [TUNNEL_NAME]
Example: sudo sh ./vpn-manager.sh status office-vpn
Restart All Tunnels:
sudo sh ./vpn-manager.sh reload
Use this if connections are down.

sudo sh ./vpn-manager.sh debug [TUNNEL_NAME]
Example: sudo sh ./vpn-manager.sh debug office-vpn
Use this to troubleshoot connection problems.
How to Find Your Tunnel Names:
Look at the "Available VPN Tunnels" section when you run the script without arguments.
The tunnel name is shown before the status (UP or DOWN).
Use these exact names when running commands.
How to Change a Tunnel's IP Address:
1. Edit the configuration file
Edit: /etc/ipsec.d/[TUNNEL_NAME].conf
Look for lines with "left=" or "right=" followed by an IP address.
Update the IP address(es) as needed.
Example: vi /etc/ipsec.d/office-vpn.conf
2. Edit the secrets file
Edit: /etc/ipsec.d/[TUNNEL_NAME].secrets
Update the IP address(es) in this file to match the configuration file.
Example: vi /etc/ipsec.d/office-vpn.secrets
3. Reload the tunnel
After making changes:
sudo sh ./vpn-manager.sh reload [TUNNEL_NAME]
Troubleshooting:
1. If a tunnel shows DOWN
Try reloading the tunnel:
sudo sh ./vpn-manager.sh reload [TUNNEL_NAME]
2. If reload doesn't work
Get debug information:
sudo sh ./vpn-manager.sh debug [TUNNEL_NAME]
3. If the tunnel is still not coming up
