## Network-Level Geo-Unblocking: Imgur in the UK
**Article:** [Imgur Geo-blocked the UK, so I Geo-unblocked My Network](https://blog.tymscar.com/posts/imgurukproxy/)
**HN Discussion:** [link](https://news.ycombinator.com/item?id=46081188) — 477 points | 163 comments
**Scenario:** UK-based Minecraft player unable to view shader previews hosted on Imgur due to regional blocking.
**Solution Highlights:**
1. **Pi-hole DNS server** — Redirect `i.imgur.com` requests to local Traefik proxy.
2. **Traefik + SNI routing** — Directs Imgur traffic into a **Gluetun** container.
3. **WireGuard VPN** — Overseas endpoint to bypass geo-block.
4. **Nginx TCP proxy** inside Gluetun — Maintains TLS end-to-end without decryption.
5. **Declarative NixOS setup** — Automated system configuration with Agenix-encrypted VPN keys.
6. **Docker Compose + systemd** — Autostart and health-check integration.
**Benefits:**
- No configuration on individual devices
- Preserves full network bandwidth for non-Imgur traffic
- Transparent, low-maintenance setup
