# GPN relay daemon — systemd unit
#
# 1. Upload the whole project to the server, e.g. /opt/gpn
#    (so /opt/gpn/web and /opt/gpn/relay both exist).
# 2. sudo cp /opt/gpn/relay/gpn-relay.service /etc/systemd/system/
# 3. Adjust the paths / User below if needed.
# 4. sudo systemctl daemon-reload && sudo systemctl enable --now gpn-relay
# 5. Open the relay UDP port range in the firewall:
#      sudo ufw allow 30000:30500/udp
#
# The daemon reads web/data/relays.json + web/data/proxies.json and forwards
# each player's UDP through the chosen SOCKS5 proxy. It picks up new routes
# automatically — no restart needed when players choose a proxy.
