+
+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
+
+想說再打個VPN tunnel 來當跳板連 ptt 好了
+
+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
+
+本來是在vultr 的VPS上面建立這個tunnel 
+
+但是那台VPS連去ptt 很頓，卡卡的
+
+所以改用google cloud platform 的free tier 來做
+
+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
+
+<!--more-->
+
+GCP的申請、設定就不多說了
+
+這次碰到的怪異現象是當wireguard 都已經設定好，client 也都連上了之後
+
+會發生client 開不了 www.google.com.tw / youtube / google map 等等google 服務的狀況
+
+VPN確定是通的，我可以在client 這邊連上其他網站，但就是google的服務開不了
+
+後來不知道是怎麼樣，突然靈機一動，因為一開始設定server/peer 都是用 10.0.0.x/24 的IP
+
+想說會不會是因為這個也是google cloud platform 預設的LAN IP 網段，所以沒辦法繞出去
+
+看一下設定，確認一下這個想法對不對，果然是這樣沒錯
+
+![](https://i.imgur.com/XkrH4Pa.png)
+
+解決方法很簡單，要不修改VPS的內部IP，要不修改wireguard的設定
+
+當然我是選擇改wireguard ，因為簡單嘛！
+
+修改後的configuration 長這樣
+```
+[Interface]
+Address = 192.168.10.1/24
+PostUp = iptables -A FORWARD -i wg0 -j ACCEPT; iptables -A FORWARD -o wg0 -j ACCEPT; iptables -t nat -A POSTROUTING -o ens4 -j MASQUERADE
+PostDown = iptables -D FORWARD -i wg0 -j ACCEPT; iptables -D FORWARD -o wg0 -j ACCEPT; iptables -t nat -D POSTROUTING -o ens4 -j MASQUERADE
+ListenPort = 12000
+PrivateKey = E..........................E
+
+#OFFICE DESKTOP
+[Peer]
+PublicKey = W...........................W
+AllowedIPs = 192.168.10.2/32
+
+#ANDROID
+[Peer]
+PublicKey = w............................w
+AllowedIPs = 192.168.10.3/32
+
+#HOME
+[Peer]
+PublicKey = 2.........................................2
+AllowedIPs = 192.168.10.4/32
+```
+
+重起wireguard (或者說重起 wg0 這個interface)之後，client 開google 網頁就正常了
+
+client 這邊，也是簡單設定一下，把要透過跳板出去的IP 改走wireguard 出去
+
+底下這個，就是把往台大(140.112.0.0) 和 term.ptt.cc(104.31.0.0)的封包改走wireguard
+
+```
+[Interface] 
+PrivateKey = e............................e
+Address = 192.168.10.2/24 
+DNS = 8.8.8.8 
+MTU = 1420 
+
+[Peer] 
+PublicKey = q...........................q
+Endpoint = public_ip_of_gcp:12000
+AllowedIPs = 140.112.0.0/16,104.31.0.0/16,192.168.10.1/32
+PersistentKeepalive = 25
+```
+
+然後看一下路由對不對
+
+```
+2019-08-16 10:34:21 [cch@hq34 ~]$ traceroute term.ptt.cc
+traceroute to term.ptt.cc (104.31.231.9), 30 hops max, 60 byte packets
+ 1  192.168.10.1 (192.168.10.1)  191.826 ms  192.556 ms  192.678 ms
+ 2  * * *
+ 3  * * *
+ 4  * * *
+ 5  104.31.231.9 (104.31.231.9)  203.918 ms  203.982 ms  203.979 ms
+2019-08-16 10:34:33 [cch@hq34 ~]$ 
+```
+
+果然是走wireguard (192.168.10.1) 出去 ，跳板成功！

+
+因為實在受夠了現在用的 openwrt + strongswan 建立 IPSec VPN
+
+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
+
+完全沒辦法了解當時設計的邏輯，造成後續debug 困難
+
+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
+
+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
+
+這次試試看躲在gateway後面，看看能不能建立多點的VPN環境

+
+
+#### additonal steps
+##### enable firewall NAT in each nodes router
+not necessary , but if the wireguard node is behind a NAT router , then must enable NAT for wireguard
+
+1.1.1.1 is the WAN IP of the router , and 192.168.80.4 is the wireguard LAN ip, I map port 224 to ssh and 12000 for wireguard
+```
+iptables -t nat -A PREROUTING -i eth1 -d 1.1.1.1 -p tcp --dport 224 -j DNAT --to-destination 192.168.80.4:22
+iptables -t nat -A PREROUTING -i eth1 -d 1.1.1.1 -p udp --dport 12000 -j DNAT --to-destination 192.168.80.4:12000
+```
+
+#### summary
+
+if want to add more nodes into VPN , just follow the logic and steps.
+```
+create private/public key
+create wg0.conf 
+add new nodes in every other nodes wg0.conf as peer
+```
+
+
+1. for route , must add remote network in AllowedIPs 
+2. check ip_forward is enable 
+3. I think the postup haws no effect here , because the firewall service was disable by default , and if I use iptables -F to flush all firewall rules , the network still remain in connected.
+4. need to create an ansible playbook for this
+
+
+#### Update
+
+##### strongswan IPSEC VS wireguard
+
+**wireguard almost twice faster than strongswan**
+
+iperf test with wireguard VPN 30 seconds benchmark
+```

+      <description>&lt;p&gt;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&lt;/p&gt;
+
+&lt;p&gt;想說再打個VPN tunnel 來當跳板連 ptt 好了&lt;/p&gt;
+
+&lt;p&gt;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&lt;/p&gt;
+
+&lt;p&gt;本來是在vultr 的VPS上面建立這個tunnel&lt;/p&gt;
+
+&lt;p&gt;但是那台VPS連去ptt 很頓，卡卡的&lt;/p&gt;
+
+&lt;p&gt;所以改用google cloud platform 的free tier 來做&lt;/p&gt;
+
+&lt;p&gt;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&lt;/p&gt;
+
+&lt;p&gt;&lt;/p&gt;</description>

+      <guid>https://h.cowbay.org/post/multiple-site-to-site-vpn-using-wireguard/</guid>
+      <description>&lt;p&gt;因為實在受夠了現在用的 openwrt + strongswan 建立 IPSec VPN&lt;/p&gt;
+
+&lt;p&gt;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&lt;/p&gt;
+
+&lt;p&gt;完全沒辦法了解當時設計的邏輯，造成後續debug 困難&lt;/p&gt;
+
+&lt;p&gt;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&lt;/p&gt;
+
+&lt;p&gt;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&lt;/p&gt;
+
+&lt;p&gt;這次試試看躲在gateway後面，看看能不能建立多點的VPN環境&lt;/p&gt;

+      <description>&lt;p&gt;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&lt;/p&gt;
+
+&lt;p&gt;想說再打個VPN tunnel 來當跳板連 ptt 好了&lt;/p&gt;
+
+&lt;p&gt;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&lt;/p&gt;
+
+&lt;p&gt;本來是在vultr 的VPS上面建立這個tunnel&lt;/p&gt;
+
+&lt;p&gt;但是那台VPS連去ptt 很頓，卡卡的&lt;/p&gt;
+
+&lt;p&gt;所以改用google cloud platform 的free tier 來做&lt;/p&gt;
+
+&lt;p&gt;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&lt;/p&gt;
+
+&lt;p&gt;&lt;/p&gt;</description>

+      <guid>https://h.cowbay.org/post/multiple-site-to-site-vpn-using-wireguard/</guid>
+      <description>&lt;p&gt;因為實在受夠了現在用的 openwrt + strongswan 建立 IPSec VPN&lt;/p&gt;
+
+&lt;p&gt;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&lt;/p&gt;
+
+&lt;p&gt;完全沒辦法了解當時設計的邏輯，造成後續debug 困難&lt;/p&gt;
+
+&lt;p&gt;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&lt;/p&gt;
+
+&lt;p&gt;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&lt;/p&gt;
+
+&lt;p&gt;這次試試看躲在gateway後面，看看能不能建立多點的VPN環境&lt;/p&gt;

+
+<p>來到這個環境之後，有一個很詭異的狀況一直困擾著我</p>
+
+<p>在每個分公司，都會有一台伺服器作為KVM Host</p>
+
+<p>上面跑兩台VM，一台作為ansible controller (目前沒作用)</p>
+
+<p>另一台作為這邊所謂的 &ldquo;Build Server&rdquo;</p>
+
+<p>用途包含了DHCP Server / Proxy Server (squid3) / APT Proxy (squid-deb-proxy)</p>
+
+<p>問題就發生在這台 Build Server 上&hellip;</p>

+各個伺服器統一備份到一台backup storage
+想說如果每天能夠看到backup storage的磁碟用量的話
+就可以抓出備份空間成長速度、推估需要多大的磁碟空間
+找了一些工具，結果發現 durep 這個 ubuntu 內建的工具
+基本上可以滿足我的需求</p>

-<p>尤其是有牽涉到從外部導入yaml檔案時，更是常常讓我不知道到底該怎麼抓出想要的變數</p>
+<p>想用PXE來處理，只要user開機按F12(acer 桌機) 選擇PXE Boot</p>
 
-<p>這次還是用selectattr 來處理，希望下次能夠記得&hellip;</p>
+<p>然後選擇OS版本，就可以自動進行安裝</p>
+
+<p>安裝完成後，會自動重新開機，接著就用ansible來做user環境設定</p>
+
+<p>PXE的部份本來是沒有什麼問題，自動安裝系統的部份都做好了</p>
+
+<p>可是因為這次的量比較多，想說讓每一台在完成PXE安裝後的第一次重開機</p>
+
+<p>就送出一封郵件來通知我，說已經完成安裝，可以執行ansible 了</p>
+
+<p>看似很簡單的一件事情，卻搞了我兩天&hellip;.</p>

+      <description>&lt;p&gt;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&lt;/p&gt;
+
+&lt;p&gt;想說再打個VPN tunnel 來當跳板連 ptt 好了&lt;/p&gt;
+
+&lt;p&gt;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&lt;/p&gt;
+
+&lt;p&gt;本來是在vultr 的VPS上面建立這個tunnel&lt;/p&gt;
+
+&lt;p&gt;但是那台VPS連去ptt 很頓，卡卡的&lt;/p&gt;
+
+&lt;p&gt;所以改用google cloud platform 的free tier 來做&lt;/p&gt;
+
+&lt;p&gt;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&lt;/p&gt;

+      <description>&lt;p&gt;因為實在受夠了現在用的 openwrt + strongswan 建立 IPSec VPN&lt;/p&gt;
+
+&lt;p&gt;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&lt;/p&gt;
+
+&lt;p&gt;完全沒辦法了解當時設計的邏輯，造成後續debug 困難&lt;/p&gt;
+
+&lt;p&gt;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&lt;/p&gt;
+
+&lt;p&gt;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&lt;/p&gt;
+
+&lt;p&gt;這次試試看躲在gateway後面，看看能不能建立多點的VPN環境&lt;/p&gt;

-
-<p>同時在圖書館內建立不同的&rdquo;書籍&rdquo;</p>
-
-<p>而且支援 Markdown 語法</p>
-
-<p>其他的方式像是在nextcloud上編輯 md檔案(字體太小)</p>
-
-<p>或者是boostnote(只能在本機)</p>
-
-<p>都或多或少有點小缺點</p>
-
-<p>Bookstack則是沒有這些問題，不過就是系統「大」了點&hellip;</p>
-
-<p>不過還好有人做成docker的方式來啟動，大大的降低了建置的難度(其實也沒有很難啦，只是要裝個PHP、弄個DB而已)</p>

+        <p>Bookstack 是一套非常好用的線上&rdquo;筆記&rdquo;系統</p>
+
+<p>他用圖書館/書本的概念，讓使用者可以建立自己的&rdquo;圖書館&rdquo;</p>
+
+<p>同時在圖書館內建立不同的&rdquo;書籍&rdquo;</p>
+
+<p>而且支援 Markdown 語法</p>
+
+<p>其他的方式像是在nextcloud上編輯 md檔案(字體太小)</p>
+
+<p>或者是boostnote(只能在本機)</p>
+
+<p>都或多或少有點小缺點</p>
+
+<p>Bookstack則是沒有這些問題，不過就是系統「大」了點&hellip;</p>
+
+<p>不過還好有人做成docker的方式來啟動，大大的降低了建置的難度(其實也沒有很難啦，只是要裝個PHP、弄個DB而已)</p>

+
+    
+        <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></p>
+
+<p>GCP的申請、設定就不多說了</p>
+
+<p>這次碰到的怪異現象是當wireguard 都已經設定好，client 也都連上了之後</p>
+
+<p>會發生client 開不了 www.google.com.tw / youtube / google map 等等google 服務的狀況</p>
+
+<p>VPN確定是通的，我可以在client 這邊連上其他網站，但就是google的服務開不了</p>
+
+<p>後來不知道是怎麼樣，突然靈機一動，因為一開始設定server/peer 都是用 10.0.0.x/24 的IP</p>
+
+<p>想說會不會是因為這個也是google cloud platform 預設的LAN IP 網段，所以沒辦法繞出去</p>
+
+<p>看一下設定，確認一下這個想法對不對，果然是這樣沒錯</p>
+
+<p><img src="https://i.imgur.com/XkrH4Pa.png" alt="" /></p>
+
+<p>解決方法很簡單，要不修改VPS的內部IP，要不修改wireguard的設定</p>
+
+<p>當然我是選擇改wireguard ，因為簡單嘛！</p>
+
+<p>修改後的configuration 長這樣</p>
+
+<pre><code>[Interface]
+Address = 192.168.10.1/24
+PostUp = iptables -A FORWARD -i wg0 -j ACCEPT; iptables -A FORWARD -o wg0 -j ACCEPT; iptables -t nat -A POSTROUTING -o ens4 -j MASQUERADE
+PostDown = iptables -D FORWARD -i wg0 -j ACCEPT; iptables -D FORWARD -o wg0 -j ACCEPT; iptables -t nat -D POSTROUTING -o ens4 -j MASQUERADE
+ListenPort = 12000
+PrivateKey = E..........................E
+
+#OFFICE DESKTOP
+[Peer]
+PublicKey = W...........................W
+AllowedIPs = 192.168.10.2/32
+
+#ANDROID
+[Peer]
+PublicKey = w............................w
+AllowedIPs = 192.168.10.3/32
+
+#HOME
+[Peer]
+PublicKey = 2.........................................2
+AllowedIPs = 192.168.10.4/32
+</code></pre>
+
+<p>重起wireguard (或者說重起 wg0 這個interface)之後，client 開google 網頁就正常了</p>
+
+<p>client 這邊，也是簡單設定一下，把要透過跳板出去的IP 改走wireguard 出去</p>
+
+<p>底下這個，就是把往台大(140.112.0.0) 和 term.ptt.cc(104.31.0.0)的封包改走wireguard</p>
+
+<pre><code>[Interface] 
+PrivateKey = e............................e
+Address = 192.168.10.2/24 
+DNS = 8.8.8.8 
+MTU = 1420 
+
+[Peer] 
+PublicKey = q...........................q
+Endpoint = public_ip_of_gcp:12000
+AllowedIPs = 140.112.0.0/16,104.31.0.0/16,192.168.10.1/32
+PersistentKeepalive = 25
+</code></pre>
+
+<p>然後看一下路由對不對</p>
+
+<pre><code>2019-08-16 10:34:21 [cch@hq34 ~]$ traceroute term.ptt.cc
+traceroute to term.ptt.cc (104.31.231.9), 30 hops max, 60 byte packets

+
+<p>果然是走wireguard (192.168.10.1) 出去 ，跳板成功！</p>

+      <description>&lt;p&gt;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&lt;/p&gt;
+
+&lt;p&gt;想說再打個VPN tunnel 來當跳板連 ptt 好了&lt;/p&gt;
+
+&lt;p&gt;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&lt;/p&gt;
+
+&lt;p&gt;本來是在vultr 的VPS上面建立這個tunnel&lt;/p&gt;
+
+&lt;p&gt;但是那台VPS連去ptt 很頓，卡卡的&lt;/p&gt;
+
+&lt;p&gt;所以改用google cloud platform 的free tier 來做&lt;/p&gt;
+
+&lt;p&gt;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&lt;/p&gt;

+      <description>&lt;p&gt;因為實在受夠了現在用的 openwrt + strongswan 建立 IPSec VPN&lt;/p&gt;
+
+&lt;p&gt;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&lt;/p&gt;
+
+&lt;p&gt;完全沒辦法了解當時設計的邏輯，造成後續debug 困難&lt;/p&gt;
+
+&lt;p&gt;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&lt;/p&gt;
+
+&lt;p&gt;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&lt;/p&gt;
+
+&lt;p&gt;這次試試看躲在gateway後面，看看能不能建立多點的VPN環境&lt;/p&gt;

+        <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>同時在圖書館內建立不同的&rdquo;書籍&rdquo;</p>
-
-<p>而且支援 Markdown 語法</p>
-
-<p>其他的方式像是在nextcloud上編輯 md檔案(字體太小)</p>
-
-<p>或者是boostnote(只能在本機)</p>
-
-<p>都或多或少有點小缺點</p>
-
-<p>Bookstack則是沒有這些問題，不過就是系統「大」了點&hellip;</p>
-
-<p>不過還好有人做成docker的方式來啟動，大大的降低了建置的難度(其實也沒有很難啦，只是要裝個PHP、弄個DB而已)</p>

+        <p>Bookstack 是一套非常好用的線上&rdquo;筆記&rdquo;系統</p>
+
+<p>他用圖書館/書本的概念，讓使用者可以建立自己的&rdquo;圖書館&rdquo;</p>
+
+<p>同時在圖書館內建立不同的&rdquo;書籍&rdquo;</p>
+
+<p>而且支援 Markdown 語法</p>
+
+<p>其他的方式像是在nextcloud上編輯 md檔案(字體太小)</p>
+
+<p>或者是boostnote(只能在本機)</p>
+
+<p>都或多或少有點小缺點</p>
+
+<p>Bookstack則是沒有這些問題，不過就是系統「大」了點&hellip;</p>
+
+<p>不過還好有人做成docker的方式來啟動，大大的降低了建置的難度(其實也沒有很難啦，只是要裝個PHP、弄個DB而已)</p>

+        <p>公司內有幾台NAS，其中有一台用來放開發人員的postgresql dump file
+之前都是主要的開發人員上傳到google drive，分享出來 ，然後其他人去抓回來</p>
+
+<p>這樣子有個問題是，當server要存取這些檔案時，就沒辦法了，除非透過一些 3rd party的軟體
+像是這篇</p>

+
+<p>但是手邊的伺服器，原則上除非有必要，不然都沒有開放internet
+所以導致明明檔案就在那邊，但是要取得就是很麻煩</p>
