Tor Relay

The source material covers configuring a Tor middle relay: a node that forwards encrypted Tor traffic between other nodes in the network without being an exit node. Running a relay contributes bandwidth to the Tor network and helps it remain fast and resilient.

This is genuinely worthwhile if it fits your situation. It does not fit this one.

Why a Tor relay is not in this series

Residential connections are not suitable relay nodes. The Tor Project’s guidance is that relays should have a static IP address, high uptime, and consistent bandwidth. Residential ISP connections in the UK typically have dynamic IP addresses, upload bandwidth significantly lower than download bandwidth, and are subject to fair use policies that a relay would likely breach. A relay running on a home connection with 50-100Mbps upload would represent a meaningful fraction of available upload bandwidth continuously, affecting everything else that uses the connection.

ISP terms of service. Most UK residential ISPs prohibit running servers that provide services to third parties. A Tor relay forwards traffic for third parties by definition. Running one on a residential connection risks account suspension.

The February server is not always on. The server is a homelab, not production infrastructure. It will be restarted for maintenance, updated, and potentially taken offline for extended periods. A Tor relay that goes offline frequently is worse for the network than no relay at all: it degrades reliability for circuits that route through it and wastes the resources of the nodes that built paths through it.

Exit relays carry legal risk. The source material specifically covers a middle relay, not an exit relay, which is the correct choice since exit relays are the nodes that make the final connection to the destination and are therefore the ones that appear in server logs. However, the legal and practical position of running any Tor relay in the UK is not straightforwardly clear, and that uncertainty is worth factoring into the decision.

If you want to run a relay

Running a Tor relay from a VPS with a static IP, generous bandwidth allowances, and appropriate terms of service is a different proposition from running one at home. Several VPS providers explicitly permit Tor relays and some actively support the Tor community.

The Tor Project maintains guidance on setting up relays:

The relay operator community is active and supportive for anyone who wants to contribute to the network from an appropriate hosting environment.

Contributing to the Tor network is a meaningful thing to do. The constraint here is the home network context, not the goal. A dedicated VPS relay with proper bandwidth and uptime is a more valuable contribution to the network than a residential relay that goes offline unpredictably and saturates a shared upload connection.
