nat-config

nat-config is a skill for Claude Code, Codex from nanxiaoyao/network-huawei-skills. It costs 109 tokens per session (1,767 once invoked), scanned A, original, MIT.

A guide for configuring and troubleshooting network address translation on Huawei USG6000E firewalls. NAT changes network addresses, such as allowing private internal devices to access the internet.

In plain words
What is it for?
Configuring source NAT, Easy-IP, NAPT, NAT Server rules, bidirectional NAT, NAT64/NAT46, CGN, and NAT diagnostics.
Why use it?
It explains the separate rules for translating outgoing traffic, exposing internal servers, and handling address pools and sessions.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

nat-config scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

华为 USG NAT 配置技能 (nat-config)

适用平台 USG6000E 系列 适用版本 V600R007C20+ 文档来源 HUAWEI USG6000E V600R007C20 产品文档

USG 的 NAT 采用策略式 NAT-Policy 与目的 NAT Server 两套独立体系 与传统路由器的 ACL+NAT 模型完全不同 本技能覆盖源 NAT 目的 NAT 双向 NAT 配置与排错

触发场景

  • 配置源 NAT 内网访问外网
  • 配置 NAT Server 外网访问内网服务器
  • 配置 Easy-IP 出接口 NAT
  • NAT 不生效排错
  • 查看 NAT 会话/地址池/统计
  • CGN 大规模 NAT 场景
  • NAT64 IPv6 转 IPv4

核心概念

USG NAT 分两大类

  • 源 NAT source NAT 转换源 IP 通常内网到外网
  • 目的 NAT destination NAT 转换目的 IP 通常外网到内网服务器即 NAT Server

源 NAT 三种模式

  • NAPT 多对多带端口转换 最常用
  • No-PAT 多对多无端口转换
  • Easy-IP 转换为出接口 IP

地址池 nat address-group 是 NAT 的核心资源

命令体系

1 NAT 策略视图 源 NAT

进入策略视图 system-view nat-policy

创建规则 rule name source-zone destination-zone source-address destination-address service action source-nat address-group action source-nat easy-ip action no-nat enable

2 地址池

system-view nat address-group [group-number] section mode pat mode no-pat local mode no-pat global mode full-cone global route enable quit

3 NAT Server 目的 NAT

基本语法 nat server [name] protocol global inside

举例 外网访问内部 web 服务器 nat server www_server protocol tcp global 1.1.1.10 80 inside 10.1.1.100 80 nat server zone untrust protocol tcp global interface GigabitEthernet1/0/1 8080 inside 10.1.1.100 80

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

nat-config is a skill published in the GitHub repository nanxiaoyao/network-huawei-skills (2 stars, last pushed 1mo ago), licensed MIT. It adds 109 tokens to every session and 1,767 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
