• OS Windows 11 (64-bit)
• CPU 64-bit processor
• Other Internet connection required

1. Communication Protocol and Direction

• NEO PDO accesses external services from your PC. No inbound connections to NEO PDO and no port forwarding are required.
• External communication uses the same encrypted protocol as ordinary web browsing (HTTPS, standard port TCP 443).
• In proxy environments, you can select “Automatic”, “Manual” or “Direct connection” on the NEO PDO settings screen. Automatic mode uses the standard proxy environment variables such as HTTP_PROXY / HTTPS_PROXY. In environments configured solely with a Windows PAC (auto-configuration script), you may need to configure the proxy server manually on the NEO PDO settings screen.
• (User option) When using Codex CLI, secure WebSocket (WSS, TCP 443) may be used in addition to HTTPS.
• (User option) When using Codex CLI or Claude Code CLI, each CLI may require its own separate proxy configuration.

3. If Firewall Rules Are Required

If PDO cannot connect in a corporate firewall environment, please take the following steps (ask your IT department if needed).

3-1. Allow HTTPS Traffic

Allow HTTPS traffic (TCP 443) to the following domains. If path-level rules are required, allow them including the wildcards shown below.

(Required for basic NEO PDO operation)

• https://rn-ip.com/*

(Required for retrieving and displaying patent documents)

• https://patents.google.com/*
• https://j-platpat.inpit.go.jp/*

(If using the translation feature)

• https://translate.googleapis.com/*
• https://api.deepl.com/* (user option: paid DeepL API)
• https://api-free.deepl.com/* (user option: free DeepL API)

(User option: using your own OpenAI API key)

• https://api.openai.com/v1/*

(User option: using your own Anthropic API key)

• https://api.anthropic.com/v1/*

(User option: using Codex CLI)

• https://chatgpt.com/*
• https://*.chatgpt.com/*
• https://openai.com/*
• https://*.openai.com/*
• https://oaistatic.com/*
• https://*.oaistatic.com/*
• https://oaiusercontent.com/*
• https://*.oaiusercontent.com/*

Codex CLI may also require secure WebSocket (WSS) traffic over TCP 443 to be allowed.

(User option: using Claude Code CLI)

• https://api.anthropic.com/*
• https://claude.ai/*
• https://console.anthropic.com/*
• https://statsig.anthropic.com/*

* Claude Code CLI may connect to Sentry-related domains for diagnostics and error reporting. Depending on your corporate security policy, your network administrator should verify the required destinations individually.

* The authentication and delivery endpoints of external AI services may be added or changed at the discretion of each service provider.

3-2. SSL Inspection Exclusion

If your corporate network performs SSL inspection, HTTPS decryption or traffic content inspection, we recommend adding the domains of the services you use — from those listed in 3-1 — to the SSL inspection exclusion list (whitelist).

NEO PDO and external AI clients validate TLS certificates. In environments where SSL inspection replaces certificates with a corporate network's own certificate, certificate errors may occur and prevent connections.

NEO PDO provides an option to disable its own certificate validation by selecting “Connect with SSL certificate validation disabled” on the SSL error screen at startup.

However, this setting applies only to HTTPS communication performed by NEO PDO itself. It does not apply to the certificate validation of external clients that run separately from NEO PDO, such as Codex CLI or Claude Code CLI.

If certificate errors occur with Codex CLI or Claude Code CLI, you will separately need to configure the corporate CA certificate for each client, or exclude the relevant domains from SSL inspection.

* Disabling SSL certificate validation makes it impossible to verify the authenticity of the communication partner, and interception or tampering by a third party may go undetected. Please use it only as a temporary workaround and only where permitted by your company's or firm's security policy. As a rule, we recommend SSL inspection exclusion or the proper configuration of a corporate CA certificate.
