Disable routing - #12
Conversation
📝 WalkthroughWalkthroughNordVPN Meshnet configuration is enhanced with explicit feature toggles (notifications, PQ, LAN discovery, technology) and Norway-specific auto-connect. Peer data extraction is refactored for consistency, peer filesharing configuration gains documentation, and exit-node peer permission loops now include self-nickname guards to prevent self-permission attempts.

- Line 39: The nordvpn command uses an unquoted shell variable; update the
invocation that calls nordvpn meshnet set nickname $NICKNAME to quote the
variable (use "$NICKNAME") so the NICKNAME variable is passed intact to the
nordvpn meshnet set nickname command and avoids word-splitting or globbing
issues.
- Around line 44-45: Update the inaccurate comment that mentions "Perfect
Forward Secrecy (PFS)": replace it with a correct description for the `pq`
setting (Post-Quantum encryption protection) so the comment accurately describes
`nordvpn set pq off` — e.g., change the comment above the `nordvpn set pq off`
command to state that it disables Post-Quantum encryption protection to improve

Quote the variable to prevent word splitting.
The $NICKNAME variable should be quoted to prevent potential issues if the nickname contains spaces or special characters.

🧩 Analysis chain
🌐 Web query:
What does the 'nordvpn set pq' command control in NordVPN?
💡 Result:
The command nordvpn set pq controls NordVPN’s post-quantum (PQ) protection setting (it enables or disables “Post-quantum encryption”). [1][2] When you run it with on/off (for example nordvpn set pq on or nordvpn set pq off), NordVPN turns that PQ protection feature on or off for subsequent connections. [1] NordVPN’s PQ feature is specifically described as “post-quantum encryption” / “post-quantum protection.” [1][2]

Correct the comment to accurately describe the pq setting.
The code comment refers to "Perfect Forward Secrecy (PFS)" but nordvpn set pq off actually disables Post-Quantum encryption protection, not PFS. These are different security mechanisms. Update the comment to say something like: # Disable Post-Quantum encryption protection to allow for better compatibility with certain devices and configurations.
