Cloudflare setup

内网穿透

Zero Trust -> Networks -> Tunnels

Zero Trust -> Access -> Tunnels(2023 old)

Create a tunnel

• Name your tunnel TEST
• Choose your environment
• Install and run a connector

# 内网主机
# https://github.com/cloudflare/cloudflared/releases/latest/download/cloudflared-linux-x86_64.rpm
# yum localinstall cloudflared.rpm
cloudflared service install <token>

每个 tunnel 均需要一个 token，如果已经建立过需要更新，那么先删除，再安装：

cloudflared service uninstall

Public hostnames

HTTP

• Add public hostname for http://localhost:8088

p88.server.com --> http://127.0.0.1:8088

SSH

• Add public hostname for localhost:22

ssh.server.com --> ssh://127.0.0.1:22

• Client

# /usr/local/bin/cloudflared
.ssh/config
Host ssh.server.com
ProxyCommand /usr/local/bin/cloudflared access ssh --hostname %h

ssh ssh.server.com

DNS

1. 在域名提供商 nameserver 中指向 cloudflare(carrera.ns.cloudflare.com, matteo.ns.cloudflare.com)
2. 在 cloudflare 建立 DNS 解析，如：A 类解析 mwbbs.eu.org 132.145.61.120。如果某些地区无法正确解析，可以选择：不通过 proxy 处理
