Windows users running Hermes in WSL2 with model servers on the Windows
host hit 'connection refused' because WSL2's NAT networking means
localhost points to the VM, not Windows.
Covers:
- Mirrored networking mode (Win 11 22H2+) — makes localhost work
- NAT mode fallback using the host IP via ip route
- Per-server bind address table (Ollama, LM Studio, llama-server,
vLLM, SGLang)
- Detailed Ollama Windows service config for OLLAMA_HOST
- Windows Firewall rules for WSL2 connections
- Quick verification steps
- Cross-reference from Troubleshooting section
