Symptom & Impact
Clients behind RRAS lose internet egress while local gateway connectivity appears normal.
Environment & Reproduction
Triggered by interface role swaps, route table drift, or accidental NAT service reset.
Root Cause Analysis
Public/private interface assignment or outbound route path is incorrect, so translation cannot be applied.
Quick Triage
Check NAT status, interface mappings, and route table defaults on the RRAS host.
Step-by-Step Diagnosis
Verify packet path from client subnet to egress interface and ensure no overlapping NAT policies conflict.
Solution – Primary Fix
Reassign correct NAT public interface, repair default route, and restart RRAS to apply consistent state.

Solution – Alternative Approaches
Use upstream firewall NAT temporarily if RRAS remains unstable during remediation window.
Verification & Acceptance Criteria
Outbound traffic is translated correctly and clients reach external endpoints without intermittent drops.
Rollback Plan
Restore previous RRAS export and route table if new NAT policy causes broader connectivity loss.
Prevention & Hardening
Track NAT configuration as code and validate interface role mapping after each network maintenance event.
Related Errors & Cross-Refs
May co-occur with VPN route leaks and firewall egress ACL misalignment.
