1701
Port 1701 carries L2TP, and NCC-1701 is the registry of the USS Enterprise.

Where 1701 fits
Why 1701 is special
Both are real and neither derives from the other. L2TP tunnels traffic but provides no encryption itself, so it is almost always paired with IPsec — a combination written L2TP/IPsec precisely because the first half is not enough alone.
Same number, different meanings
How 1701 is understood across different contexts — never implying one meaning because of another.
- Mathematics
Both are real and neither derives from the other. L2TP tunnels traffic but provides no encryption itself, so it is almost always paired with IPsec — a combination written L2TP/IPsec precisely because the first half is not enough alone.
- Technology & computing
L2TP creates a tunnel and provides no encryption of its own, so it is deployed almost exclusively as L2TP/IPsec. Writing the pair as one name is an admission that the first half is not sufficient alone.
- Media & popular culture
NCC-1701 is the USS Enterprise's hull registry, and the digits alone are recognised well beyond people who watch the programme. Its designer said he chose 1701 to be unmistakable on screen at low resolution, which is an unusually practical origin for a piece of fiction.

Related numbers & connections
L2TP provides a tunnel with no encryption of its own, so it is deployed as L2TP/IPsec. OpenVPN bundles both functions, which is why it needs only one port.
