<p>最近一直在玩 wireguard ，先前把各個分公司和總部的VPN 改用 wireguard 建立</p>
<p>想說再打個VPN tunnel 來當跳板連 ptt 好了</p>
<p>因為wireguard 建立很簡單，而且又可以指定想要繞出去的路由，不會影響原本的網路環境</p>
<p>本來是在vultr 的VPS上面建立這個tunnel</p>
<p>但是那台VPS連去ptt 很頓，卡卡的</p>
<p>所以改用google cloud platform 的free tier 來做</p>
<p>反正只是拿來當跳板，不會有什麼流量、運算產生，可以一直保持免費的狀態</p>

<p>因為實在受夠了現在用的 openwrt + strongswan 建立 IPSec VPN</p>
<p>雖然說其實沒有什麼不好，但是畢竟不是我建立的，而當初的文件也都不見了</p>
<p>完全沒辦法了解當時設計的邏輯，造成後續debug 困難</p>
<p>可以想像一下，一台VPN router ping 不到remote、ping不到internet、甚至ping不到自己 是要怎麼debug !?(翻桌</p>
<p>之前買了兩台edgerouter X 拿來玩了一下 wireguard，感覺還不錯，不過只有測試到點對點</p>
<p>這次試試看躲在gateway後面，看看能不能建立多點的VPN環境</p>

<p>之前總部和分公司之間 是用buffalo 的小AP 灌 openwrt</p>
<p>然後用strongswan 來打 IPSEC site to site VPN</p>
<p>config 看起來不是很難 (只是看起來)</p>
<p>但是實際上已經找不到當初的文件</p>
<p>所以要維護很困難(光那些RSA KEY 就不知道為何、如何產生)</p>
<p>後來採購了兩台edgerouter X 做測試</p>
<p>也用openvpn 成功的建立了 site to site VPN</p>
<p>本來想說 openvpn 已經夠簡單了</p>
<p>今天看到文章說用wireguard 可以更簡單</p>
<p>於是研究了一下，發現還真的很簡單！</p>
