## 3. 端口转发

为了其他客户端可以通过链接访问到上图启动的 ganache，请参考 [ChainIDE - 端口转发](/chainide-chinese/5.-port-forwarding.md) 转发 HTTP 8545 端口，并复制其地址 (例如：<https://sandbox-1e82a87a951241179f98494a6dbb2617-ethereum-8545.uat-sandbox.chainide.com>)。

{% hint style="info" %}
这样你就成功的启动了一条 ganache 本地区块链。接下来可以通过 Metamask 连上该条链，或者通过 Truffle, Hrdhat 部署合约, chain id 为 1337。
