Hello there, I’m a Cisco SD-WAN specialist with hands-on experience troubleshooting vManage, vBond, and vSmart behind NAT/firewalls, including UniFi gateways and public IP transitions. I can stabilize your control plane by correcting vBond public/NAT settings, port offsets, certificates, MTU, and NAT hairpin issues, and ensure clean TLS/DTLS connectivity. I’ll apply the required changes directly on the controllers, validate control connections, and confirm WAN Edge onboarding. You’ll receive step-by-step guidance, the final firewall/NAT rule set, and a brief summary of all commands and changes made. I’ll stay engaged until the control plane remains stable for 24 hours. Ready to start immediately.

I’ve gone through your architecture and the problem description carefully, and this is a classic Cisco SD-WAN control-plane instability caused by NAT, port-offsets, and hairpinning behavior. I have hands-on experience with vManage, vBond, and vSmart deployments behind firewalls (including UniFi) and have fixed similar issues where DTLS/TLS sessions flap due to public IP mapping, loopback NAT, or certificate/MTU mismatches. My approach will be structured and practical: Validate vBond public IP, port-offsets, and control-connections Fix NAT hairpin/loopback by correcting controller reachability (system-ip, local-interface, or split-DNS where required) Verify all required Cisco SD-WAN ports, MTU, and TLS/DTLS timers on the firewall Re-check controller certificates, time sync, and control-plane bindings Stabilize OMP sessions so vSmart and vManage remain consistently up I’ll make hands-on changes with you, not just suggestions. Once complete, I’ll provide a short document covering: Final firewall/NAT rules Controller commands used Validation checks I consider the task complete only after the controllers stay stable for 24 hours and WAN edges onboard successfully. Happy to start immediately and work with you live if required.
