NIP-9 proposes updating the Nym exit policy to open TCP ports 119 and 563, allowing NymVPN users to access Usenet while maintaining privacy and network security.
Motivation
The Nym exit policy defines which ports are accessible on exit nodes to ensure privacy, security, and reliable service.
Usenet requires TCP ports 119 and 563. Currently, these ports are blocked, limiting NymVPN users who rely on Usenet. Opening these ports improves usability without compromising privacy or security.
This update will follow operator governance, consistent with previous exit policy changes (example).
Since NIP-1, exit policy decisions are managed via Nym Governator to ensure transparency and accountability.
Proposal to Enable Ports for NymVPN Users
Allow access to Usenet services through TCP ports:
*:119
*:563
Voting options
Voting takes place at Nym Governator. Proposed options:
- YES: Approve opening ports
119and563. - NO: Reject the proposal entirely.
Submit any concerns with supporting documentation for review before finalizing.
Process
If the vote meets quorum and a majority approves:
- A pull request will update the exit policy.
- The Network Tunnel Manager (NTM) will be updated to allow operators to configure WireGuard exit policy ports in line with the Mixnet policy.
Background
The Nym exit policy protects operators and users by controlling accessible ports.
Previously, Network Requesters used a centralized allow list. To decentralize control and enhance privacy, Nym transitioned to a deny list, forming the current exit policy.
Exit nodes in Gateway mode act both as:
- SOCKS5 Network Requesters
- Exit nodes for IP traffic from mixnet and VPN clients
Applying a uniform policy ensures reliable, privacy-preserving service for all NymVPN users.
