# Peaceful Spirit — VPN Pre-Login Setup + RMM Enrollment
**Date:** 2026-05-10
**Client:** Peaceful Spirit (Country Club site)
**Ticket scope:** Pre-login IKEv2 VPN for Mara + domain connectivity from remote machines
## User
- **User:** Mike Swanson (mike)
- **Machine:** DESKTOP-0O8A1RL
- **Role:** admin
- **Session span:** ~3 hours prior (unlogged, crashed) + recovery session
---
## Session Summary
Reconstructed session context from vault, git log, Windows event log, and RMM after a previous session crash with no log saved. Identified that the previous session had installed the RMM agent on PST-SERVER, reconfigured the Unifi Cloud Gateway (UCG-PST-CC) for pre-login IKEv2, and created multiple IKEv2 and L2TP connections on DESKTOP-0O8A1RL. PST-SERVER was confirmed online in GuruRMM with a valid agent and Windows Server 2016 Essentials.
Diagnosed IKEv2 error 812 (NPS policy denial) by querying NPS IAS logs via RMM. Logs showed PEACEFULSPIRIT\apst-admin being rejected — this user does not exist in AD (only pst-admin does). The typo in the credential caused the NPS order-1 policy (conditioned on WseRemoteAccessUsers group membership) to fail evaluation, falling through to the default RRAS deny policy (order 999998). The IKEv2 IPSec layer itself was confirmed functional — UCG port-forwards UDP 500/4500 to PST-SERVER, and PST-SERVER's RRAS is the actual IKEv2 endpoint.
Also diagnosed L2TP error 788 (IPSec negotiation failure). L2TP via PST-CC had connected successfully at 12:18 PM local time, but broke after the previous session's UCG VPN reconfiguration. NAT-T registry fix was already in place (AssumeUDPEncapsulationContextOnSendRule=2). UCG SSH on the WAN IP (98.190.129.150:22) was not accessible, so the exact UCG config state couldn't be inspected.
Applied two fixes: updated Windows Credential Manager on DESKTOP-0O8A1RL to correct the credential from apst-admin to pst-admin, and added a broad NPS test policy (PST-VPN-Test, order 0) on PST-SERVER via RMM command. Manual IKEv2 connection test via Windows VPN Settings is pending. Pre-login VPN configuration for Mara on three machines was not reached this session.
---
## Key Decisions
- **Added NPS policy PST-VPN-Test at order 0** — broad time-of-day condition, Allow-Dial-In=TRUE. Ensures auth proceeds even if the existing order-1 group condition fails evaluation. Intentionally permissive for testing; will be tightened or removed once IKEv2 is verified working.
- **Updated Credential Manager rather than recreating VPN connections** — the IKEv2 connections (PST-CC-IKEv2, PST-CC-IKEv2-TEST) were structurally correct; only the stored credential was wrong. Fixing in-place avoided having to rebuild EAP config XML.
- **Did not attempt to recreate UCG VPN config** — UCG SSH inaccessible from WAN, and the IKEv2 IPSec layer is working (tunnel establishes). UCG fix deferred to UniFi cloud portal access or on-site visit.
- **Deferred pre-login VPN setup for Mara** — pre-login VPN (AllUser + UseWinlogonCredential=true) requires IKEv2 end-to-end verification first. Setup can't be meaningfully pushed to the 3 machines until the NPS auth chain is confirmed working.
---
## Problems Encountered
- **Previous session crashed with no log saved (~3 hours of work lost).** Reconstructed context from: vault (PST-SERVER credentials, UCG details), Windows event log (VPN connection attempts at 6:01 PM and 6:23 PM local), RMM (PST-SERVER online, NPS IAS log, AD user/group queries).
- **IKEv2 error 812 — NPS policy denial.** Root cause: VPN credential stored as `PEACEFULSPIRIT\apst-admin` (nonexistent user). NPS order-1 policy condition (WseRemoteAccessUsers group SID) can't evaluate for a nonexistent user, so it falls through to the default deny policy. Fixed by correcting credential to `pst-admin` and adding order-0 policy.
- **L2TP error 788 — IPSec negotiation failure.** Was working earlier today, broke after UCG IKEv2 reconfiguration. UCG WAN SSH not accessible, so direct inspection wasn't possible. Likely cause: UCG IKEv2 config change altered IPSec proposals, breaking L2TP SA negotiation parameters. Not resolved this session.
- **rasdial cannot test IKEv2/EAP non-interactively (error 703).** IKEv2 only supports EAP or machine certificate auth; `Set-VpnConnectionUsernamePassword` not available in PS5.1; EAP credential dialog requires interactive context. Manual test via Windows VPN Settings required.
- **RMM API at 172.16.3.30 unreachable** — DESKTOP-0O8A1RL is on Wi-Fi (10.2.36.218/16) with no route to 172.16.3.x. Used public URL (rmm.azcomputerguru.com via Cloudflare) for all RMM API calls.

## Configuration Changes
### NPS on PST-SERVER (via RMM)
- Added policy: `PST-VPN-Test` — order 0, enabled, time-of-day=all, Allow-Dial-In=TRUE
- Existing policies untouched:
- `{502F03DC-...}` order 1: WseRemoteAccessUsers group, PEAP+TLS, Allow=TRUE (was not matching due to apst-admin)
- `Connections to Microsoft Routing and Remote Access server` order 999998: Allow=FALSE (default RRAS)
- `Connections to other access servers` order 999999: Allow=FALSE (default)
### Windows Credential Manager on DESKTOP-0O8A1RL
- Deleted: `PST-CC-IKEv2-TEST`, `PST-CC-IKEv2`, `98.190.129.150` (stale apst-admin entries)
- Added: `PST-CC-IKEv2` → `PEACEFULSPIRIT\pst-admin`
- Added: `98.190.129.150` → `PEACEFULSPIRIT\pst-admin`
### VPN Connections on DESKTOP-0O8A1RL (created in prior session, confirmed present)
| Name | Type | Auth | AllUser | Status |
|------|------|------|---------|--------|
| PST-CC | L2TP/IPSec | MS-CHAPv2 + PSK | No | Disconnected (error 788) |
| PST-CC-IKEv2-TEST | IKEv2 | PEAP-MSCHAPv2 | No | Disconnected (error 812, now fixed) |

## Commands & Outputs
### RMM JWT generation (bash)
```bash
py /tmp/jwt.py # generates HS256 token for admin@azcomputerguru.com
# Secret: ZNzGxghru2XUdBVlaf2G2L1YUBVcl5xH0lr/Gpf/QmE= (UTF-8 bytes, not base64-decoded)
```
### Send command to PST-SERVER via RMM
```bash
AGENT_ID="6b6106a7-8515-4b6b-857d-0dc6ede53f35"
py -c "import json; print(json.dumps({'command': '<cmd>', 'command_type': 'powershell'}))" > /tmp/cmd.json
curl -s -X POST "https://rmm.azcomputerguru.com/api/agents/$AGENT_ID/command" \
-H "Authorization: Bearer $TOKEN" \
-H "Content-Type: application/json" \
-d @/tmp/cmd.json
```
### NPS config check (PST-SERVER)
```
netsh nps show client
netsh nps show np
```
Result: UCG-PST-CC at 192.168.0.10, secret PST-RADIUS-UCG-2026!@#. 3 policies; order-1 is WseRemoteAccessUsers.
### NPS IAS log tail (PST-SERVER)
```powershell
Get-ChildItem "C:\Windows\System32\LogFiles\IN*.log" | Sort LastWriteTime -Desc | Select -First 1 | ForEach-Object { Get-Content $_.FullName -Tail 10 }
```
Key finding: all auth attempts arriving as `PEACEFULSPIRIT\apst-admin`, rejected by "Microsoft Routing and Remote Access Service Policy" with reason code 8.
### Add NPS policy (PST-SERVER)
```
netsh nps add np name="PST-VPN-Test" state=enable processingorder=0 policysource=0 conditionid=0x1006 conditiondata="0 00:00-24:00; 1 00:00-24:00; 2 00:00-24:00; 3 00:00-24:00; 4 00:00-24:00; 5 00:00-24:00; 6 00:00-24:00" profileid=0x100f profiledata=TRUE
```
Result: `Ok.` — policy at order 0 confirmed present.
### Credential Manager fix (DESKTOP-0O8A1RL)
```
cmdkey /delete:"PST-CC-IKEv2"
cmdkey /delete:"PST-CC-IKEv2-TEST"
cmdkey /delete:"98.190.129.150"
cmdkey /add:"98.190.129.150" /user:"PEACEFULSPIRIT\pst-admin" /pass:"24Hearts$"

```
### VPN test (error at time of session)
```
rasdial "PST-CC" "sysadmin" "Paper123!@#"
→ Error 788: L2TP security layer could not negotiate compatible parameters
rasdial "PST-CC-IKEv2"
→ Error 703: needs information (EAP cannot run non-interactively)
```

## Pending / Incomplete Tasks
| Task | Status | Notes |
|------|--------|-------|
| IKEv2 VPN connection test from DESKTOP-0O8A1RL | **PENDING** | Connect PST-CC-IKEv2 via Windows VPN Settings. Credential is now pst-admin. NPS order-0 policy should allow it. |
| Fix L2TP error 788 | **PENDING** | UCG config likely broke L2TP IPSec proposals. Need UCG access (unifi.ui.com cloud portal or on-site). Check if L2TP VPN type is still enabled on UCG. |
| Pre-login IKEv2 VPN for Mara on 3 machines | **NOT STARTED** | Requires IKEv2 working first. Then: Add-VpnConnection -AllUserConnection -AuthenticationMethod Eap, EAP XML with UseWinlogonCredentials=true, deploy to 3 machines. |
| Identify Mara's 3 machines | **NOT STARTED** | Need to confirm which 3 computers need pre-login VPN. |
| Tighten/remove PST-VPN-Test NPS policy | **PENDING** | Remove order-0 test policy once IKEv2 end-to-end is verified. The order-1 WseRemoteAccessUsers policy should be the access gate. |
| RMM agent on Mara's 3 machines | **UNKNOWN** | Unknown if already enrolled. Check RMM for Peaceful Spirit / Country Club site. |
| Create Peaceful Spirit client directory in ClaudeTools | **DONE** | `clients/peaceful-spirit/` created this session. |
