我在 openvpn 的实现上遇到了问题所以我在这里,希望有人能帮助我

故事:

我在 ubuntu 服务器 VPS 上安装了 openvpn 服务器,我使用 tun 点对点而不是 tap 网桥。没有服务器配置错误导致的错误。

当我在客户端发出 openvpn client.conf 命令时,它会给我:

Thu Oct 27 15:17:39 2011 OpenVPN 2.1.0 i686-pc-linux-gnu [SSL] [LZO2] [EPOLL] [PKCS11] [MH] [PF_INET6] [eurephia] built on Jul 12 2010

当我用谷歌搜索这个问题时,我发现人们和 openvpn 手册本身都说这是由服务器的防火墙配置引起的

这是我的规则:

iptables -A INPUT -p tcp --dport 4242 -j ACCEPT
iptables -A OUTPUT -p tcp --sport 4242 -j ACCEPT
iptables -A FORWARD -m state --state RELATED,ESTABLISHED -j ACCEPT
iptables -A FORWARD -s 10.8.0.0/24 -j ACCEPT
iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -j SNAT --to VPS_IP_ADDR
