Retire the tinyproxy HTTP container (tinyproxy has no per-source-IP conditional auth) and serve both the HTTP proxy (:3128) and SOCKS5 (:1080) from a single 3proxy instance. LAN (192.168.0.0/22) stays passwordless; any non-LAN source (i.e. external clients via the router port-forward) must authenticate. Credentials live in a host-only /etc/3proxy/3proxy.secret (0600, not in git), included by 3proxy.cfg. A deny rule on the gateway IP makes the proxy fail closed if the port-forward ever SNATs to 192.168.0.1. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

# Unified LAN proxy for the tekhnohim Tailscale exit-node egress.

#
|
|
# One 3proxy instance serves BOTH an HTTP proxy (:3128) and a SOCKS5 proxy
|
|
# (:1080), each chained to the Tailscale userspace SOCKS5 (ts-proxy:1055) so
|
|
# clients exit the internet as the Hetzner exit-node IP (89.167.72.79).
|
|
# TCP only (Tailscale userspace SOCKS5 has no UDP ASSOCIATE -> no QUIC/HTTP3).
|
|
#
|
|
# Access model (LAN free, outside password):
|
|
# * LAN 192.168.0.0/22 -> authorised by source IP, NO password.
|
|
# * everyone else -> must authenticate (external clients arriving via
|
|
# the router port-forward keep their public source
|
|
# IP, so they fall through to the password rule).
|
|
# The username/password lives in a host-only file (0600, NOT in git), mounted
|
|
# separately and pulled in with the include below - same pattern as ts.env.
