openVPN:如何在客户端之间建立连接?
openVPN: how to establish a connection between clients?
这个周末我正在研究我的两个 raspberry Pi(B 和新型号 2)之间的 VPN 连接。我为此选择了 openVPN。都 运行 Raspbian 气喘吁吁。
所以我的设置如下:
|B|在家里连接到互联网(DSL,静态 IP)。
另一个 Pi |2|我随身带着它通过 UMTS 路由器连接到互联网。这出乎意料地好:)
在家里|B|我有一个服务器 运行 和 |2|登录没有任何问题。
我想问你们的问题是:
我如何从我的本地网络(与 PI |B| 相同)连接,比如从我的 iPhone 连接到 |2|哪个已经打开了到 |B| 的连接?
我这样配置我的服务器:
dev tun
proto udp
port 34345
ca /etc/openvpn/easy-rsa/keys/ca.crt
cert /etc/openvpn/easy-rsa/keys/server.crt
key /etc/openvpn/easy-rsa/keys/server.key
dh /etc/openvpn/easy-rsa/keys/dh1024.pem
user nobody
group nogroup
server 10.8.0.0 255.255.255.0
persist-key
persist-tun
status /var/log/openvpn-status.log
verb 3
client-to-client
push "redirect-gateway def1 bypass-dhcp"
#set the dns servers
push "dhcp-option DNS 8.8.8.8"
push "dhcp-option DNS 8.8.4.4"
log-append /var/log/openvpn
comp-lzo
duplicate-cn
keepalive 10 120
这是我的客户端配置:
dev tun
client
proto udp
remote {myIP} 34345 #same port as on the server
resolv-retry infinite
nobind
persist-key
persist-tun
ca /home/pi/vpn/ca.crt
cert /home/pi/vpn/raspi.crt
key /home/pi/vpn/raspi.key
comp-lzo
verb 3
正如我所说,连接运行良好,如果我在新树莓派上的控制台内发出 "curl www.echoip.net/plain",我会取回我的静态 IP 地址。所以我想总的来说它是有效的。
我已经尝试访问 10.8.0.* 但这没有用,我想不出为什么?
有什么想法吗?
提前致谢,
菲利克斯

为了访问你的树莓派 |2|来自其他 VPN 客户端的客户端(在您的情况下是 iphone),您必须知道树莓派 |2| 的 IP 地址客户。在您当前的场景中,动态 IP 地址分配给 RPi |2|客户端每次与服务器建立新连接时。
为了解决这个问题,RPi必须使用静态IP地址|2|客户。可以找到设置特定客户端静态 IP 地址的过程 here.
