Cause: GitHub's servers may be throttling or your network has restrictions.
Solution: Use a download manager or mirror from a trusted academic source (e.g., University of Florida’s open-source mirror).
Once the download is complete, double-click the installer and follow the on-screen instructions. On Windows, you may see a SmartScreen warning—click "More info" and then "Run anyway" since IPOP is an open-source tool that modifies network settings.
You can connect Docker containers to your IPOP virtual network using --network host. This allows containers to see peer devices directly.
Instead of risking an obsolete tool, consider these actively maintained, secure alternatives:
| Tool | Key Feature | Best For | |------|-------------|-----------| | Tailscale | Zero-config WireGuard + P2P | Teams & homelabs | | ZeroTier | Global virtual Ethernet switch | Complex network topologies | | Nebula | Scalable P2P VPN from Slack | Self-hosters | | Tinc VPN | Full mesh routing | Linux enthusiasts |
All of the above offer NAT traversal and are updated regularly.
