Committable VPS artifacts for the native reverse-tunnel (no live-ops, no secrets):
- gen-device-ca.sh: EC P-256 self-signed device CA (CA:TRUE pathlen:0, keyCertSign+cRLSign),
openssl ca db + empty CRL, idempotent, --kind frp-client scaffolds the control-channel CA.
- issue-device-cert.sh: P-256 leaf, EKU=clientAuth only, 825d, emits .p12 (-legacy) + .pem/.key/.fullchain,
copy_extensions=none prevents CSR-injected serverAuth/CA:TRUE; CN traversal guard.
- revoke-device.sh: openssl ca revoke -> regenerate crl.pem (revocation enforced via -crl_check).
- frp/{frps.toml.example,frpc.example.toml}: control-channel mTLS+token, disableCustomTLSFirstByte=true.
- nginx/frp-mtls.conf: :8470 TLS-term, ssl_verify_client on + device-CA + ssl_crl, WS-upgrade proxy to :7080.
- nginx/stream-sni-additions.md: the two additive SNI map lines (merge-only, coexistence-safe).
Verified: gen->issue->openssl verify->revoke->CRL chain green in a tmp dir (OpenSSL 3.0.18).

# frp-mtls.conf — nginx :8470 TLS-termination + device-CA mTLS + WS-upgrade proxy to frps vhost.
|
|
#
|
|
# Native mTLS tunnel · V4. Install target: /etc/nginx/conf.d/frp-mtls.conf
|
|
# This is a conf.d snippet (safe to ADD — it only introduces a NEW loopback :8470 server + one map;
|
|
# it does NOT touch the existing stream :443 map, which is edited separately per stream-sni-additions.md).
|
|
#
|
|
# Data-path security gate: `ssl_verify_client on` against the DEVICE CA (with CRL) is the ONE gate for
|
|
# the tunnelled base app. `on`, NEVER `optional` (PLAN P-D / R2). The public :8470 SERVER cert is the
|
|
# LE wildcard (V3); the CLIENT trust anchor is the private device CA (V2) — two different chains.
|
|
#
|
|
# nginx 1.24: there is NO standalone `http2` directive here and NO `http2 off;` — HTTP/2 is off by
|
|
# default on this listen and `http2 off;` is INVALID on 1.24 (would fail `nginx -t`, PLAN R7).
