================================================

IPsec VPN server is now ready for use!

Connect to your new VPN with these details:

Server IP: XXXXXXX
IPsec PSK: abcdefgh123456
Username: lei
Password: abcdefgh123456

Additional VPN users (username | password):
user1 | pass1
user2 | pass2

Write these down. You'll need them to connect!

VPN client setup: https://vpnsetup.net/clients2

客户端用ipsec cisco连接成功，但是只能ping通 172.17.0.1
其他ip 包括 172.17.0.3 223.5.5.5 还有 docker宿主机的ip都不通

同样配置文件 在之前的docker镜像是正常的，但是刚看来一下旧版的镜像从hub.docker.com 找不到。

@joyanhui 你好！本项目最近升级到了 Alpine Linux 3.19。你可以从源代码构建之前的 Alpine 3.18 版本的镜像：

# Clone the repository
git clone https://github.com/hwdsl2/docker-ipsec-vpn-server
cd docker-ipsec-vpn-server
# Go back to the state on Dec. 20, 2023
git checkout 2db2b40df017ab42605e354cfeaca71811b7822c
# To build Alpine-based image (note the dot "." at the end)
docker build -t hwdsl2/ipsec-vpn-server .
# Or, to build Debian-based image
docker build -f Dockerfile.debian -t hwdsl2/ipsec-vpn-server:debian .

完成后，删除并重新创建 Docker 容器。重新连接 VPN。

另外，你也可以尝试不使用 host network 模式 创建 Docker 容器。在某些情况下，使用该模式可能导致 IPTables 规则的问题。

如果你有新的信息可以继续在这里回复。

感谢您的帮助，我找到到了旧版的镜像，重新部署了。
