💾 SSH Route Switcher

Route SSH hosts through a VPN interface to bypass network conflicts when your local network overlaps with remote SSH destinations.

✨ Features

• Interactive interface selection - Lists all network interfaces with IP addresses for easy VPN selection
• Automatic SSH config parsing - Reads HostName entries from your SSH config file
• Route management - Adds routes with ip route add <ip> dev <interface> metric 10
• DNS resolution - Resolves hostnames to IPs if your SSH config uses domain names
• Duplicate detection - Skips routes that already exist
