Publish Telemt's container metrics port 9090 as 192.168.0.35:9092 because Cockpit already owns host port 9090. Bind the application listener to 0.0.0.0 inside the container and restrict Telemt's metrics whitelist to the client-02 Zabbix server at 192.168.0.34/32.\n\nDocument the Zabbix template macro URL and the Telemt 3.4.25 loopback-binding gotcha. The live endpoint returned HTTP 200 with 40,235 bytes from the Zabbix server; Telemt remained healthy and rebuilt its Telegram DC connections in six seconds.
alexbers/mtprotoproxy's Fake-TLS handshake was rejected by real Telegram
clients (server/clock/secret/egress all verified good), so replace it with
Telemt (ghcr.io/telemt/telemt:3.4.25) - the same proven implementation as the
Hetzner endpoint. Config: Fake-TLS on :1080, use_middle_proxy=false (direct-to-DC,
required with a SOCKS5 upstream) and [[upstreams]] socks5 ts-proxy:1055 so only
DC-bound traffic exits via the Tailscale exit node. Secret in host-only
telemt.toml; config.py.example (alexbers) removed. Telemt stays on json-file
(its tracing logs don't ship cleanly via the syslog driver).
Dashboard: retarget the working 3proxy queries from :1080 to the HTTP front
:3128 (the old HTTP section used stale tinyproxy patterns), drop the retired
SOCKS5 section, add a Telegram/Telemt info panel.
