OpenConnect (ocserv) 已在客户端连接，但无法打开任何网页（无互联网）

请查看这些链接：
openconnect / ocserv
openconnect / ocserv 安装 - CentOS、RHEL、Fedora
我有 centos 7.6 作为服务器公网 IP。
此外，在客户端机器上，我安装了带有无线互联网的 Windows 7 操作系统。
我按照以下命令在服务器机器上安装 openconnect：

sudo yum -y install gnutls-devel libev-devel tcp_wrappers-devel pam-devel lz4-devel libseccomp-devel readline-devel libnl3-devel krb5-devel radcli-devel
sudo yum -y install epel-release
sudo yum repolist enabled
sudo yum info ocserv
sudo yum -y install ocserv
sudo ocpasswd -c /etc/ocserv/ocpasswd test
123
nano -K /etc/ocserv/ocserv.conf

这是 ocserv.conf 文件：

auth = "plain[passwd=/etc/ocserv/ocpasswd]"

# Routes to be forwarded to the client. If you need the
# client to forward routes to the server, you may use the 
# config-per-user/group or even connect and disconnect scripts.
#
# To set the server as the default gateway for the client just
# comment out all routes from the server, or use the special keyword
# 'default'.

#route = 10.10.10.0/255.255.255.0
#route = 192.168.0.0/255.255.0.0
#route = fef4:db8:1000:1001::/64

编辑 ocserv.conf 后，我执行了以下命令：

sudo systemctl start ocserv
sudo systemctl enable ocserv
sudo systemctl status ocserv

现在我从这里在客户端机器上。客户端机器可以使用用户名成功
连接到 openconnect 。 但问题是我无法在客户端机器上打开任何网页，而且似乎有。 我应该在服务器机器上做什么来解决这个问题？test
NO INTERNET


服务器和客户端的防火墙都已关闭。
我没有做任何路由或转发方面的工作。
我不熟悉它们。
如果有必要，请告诉我我应该怎么做？
我还发现了这个关联关于我的情况。但不满足...

答案1

您必须为 MASQUERADE 添加 iptables/firewall，此防火墙规则将使您的服务器成为 NAT 转换器

iptables -A INPUT -o eth0 -j ACCEPT
iptables  -A INPUT -p udp -m udp -i eth0 --dport 8090 -j ACCEPT
iptables  -A INPUT -p tcp -m tcp -i eth0 --dport 8090 -j ACCEPT
iptables  -A POSTROUTING -s 192.168.102.0/24 -o eth0 -j MASQUERADE

答案2

打开防火墙，并允许 udp/tcp 上的端口 8090
