+### Features
 
-
+- allow VPN target profiles to grant routes by live client source IP (vpn)
-
+  - Add an opt-in target profile flag that evaluates non-vpnOnly route source security against the VPN client's real connecting IP.
-
+  - Track live VPN client source IPs from smartvpn remote addresses and WireGuard peer endpoints, refreshing routes when they change.
-
+  - Expose the setting and current source IPs in the Ops UI with regression coverage for source-IP matching behavior.

+  - track live client source IPs from VPN remote addresses and WireGuard peer endpoints and re-apply routes when they change
+  - expose source IP access settings and current client source IPs through the ops API and UI
+  - add regression tests for source-IP route matching, block-list handling, vpnOnly exclusions, and WireGuard endpoint refresh

+## VPN Target Profiles
+
+Target profiles define what a VPN client can reach through `domains`, direct `targets`, and `routeRefs`. Set `allowRoutesByClientSourceIp: true` on a target profile when a VPN client should also reach non-`vpnOnly` routes that would have allowed the client's real connecting IP without the VPN.
+
+dcrouter evaluates the live source IP reported by the VPN transport, such as `remoteAddr` or the WireGuard peer endpoint. If the route source policy allows that real IP, dcrouter injects the client's assigned VPN IP into SmartProxy for that route. The source-IP grant is live-only and is removed or updated when the VPN client disconnects or changes peer endpoint.
+
+```typescript
+const targetProfile = {
+  name: 'ops laptop source access',
+  allowRoutesByClientSourceIp: true,
+};
+```
+
 ## Automation API
 
 The OpsServer exposes TypedRequest handlers at `/typedrequest`. You can use raw contracts or the object-oriented API client.
