#NAME?-juniper ipsec vpn配置-zyxel vpn

在配置Juniper IPSec VPN和Zyxel VPN时，需要确保两个设备的兼容性和正确的配置步骤，下面是一个基本的配置指南，用于设置Juniper设备和Zyxel设备之间的IPSec VPN连接。

Juniper IPSec VPN配置

1、定义IKE（Internet Key Exchange）策略：

```shell

set security ike policy ike-policy-1 mode main

set security ike policy ike-policy-1 proposals proposal-1

set security ike policy ike-policy-1 proposals proposal-1 protocol esp

set security ike policy ike-policy-1 proposals proposal-1 authentication method pre-shared-keys

set security ike policy ike-policy-1 proposals proposal-1 encryption-algorithm aes-128-cbc

set security ike policy ike-policy-1 proposals proposal-1 hash-algorithm sha1

set security ike policy ike-policy-1 lifetime seconds 86400

```

2、定义IPSec策略：

```shell

set security ipsec policy ipsec-policy-1 perfect-forward-secrecy 3

set security ipsec policy ipsec-policy-1 proposals proposal-1

set security ipsec policy ipsec-policy-1 proposals proposal-1 protocol esp

set security ipsec policy ipsec-policy-1 proposals proposal-1 encryption-algorithm aes-128-cbc

set security ipsec policy ipsec-policy-1 proposals proposal-1 authentication-algorithm hmac-sha1-96

set security ipsec policy ipsec-policy-1 proposals proposal-1 lifetime-seconds 3600

```

3、定义VPN对等体：

```shell

set security ike proposal proposal-1 protocol esp

set security ike proposal proposal-1 encryption-algorithm aes-128-cbc

set security ike proposal proposal-1 dh-group 5

set security ike proposal proposal-1 authentication-method pre-shared-keys

set security ike proposal proposal-1 lifetime-seconds 3600

```

4、配置VPN隧道接口：

```shell

set interfaces vt-0 family inet address <IP-Address>/32

set interfaces vt-0 ike gateway ike-gateway-1

set interfaces vt-0 ipsec policy ipsec-policy-1

```

5、配置IKE对等体：

```shell

set security ike gateway ike-gateway-1 address <Zyxel-Public-IP>

set security ike gateway ike-gateway-1 external-interface <Interface>

set security ike gateway ike-gateway-1 ike-policy ike-policy-1

set security ike gateway ike-gateway-1 pre-shared-key ascii-text <Pre-Shared-Key>

```

Zyxel VPN配置

1、启用IPSec VPN：

- 进入VPN设置。

- 选择“IPSec VPN”并启用。

2、配置IPSec VPN连接：

- 添加新的IPSec VPN连接。

- 输入Juniper设备的公网IP地址作为“远程网关”。

- 输入预共享密钥（与Juniper设备上的相同）。

3、配置加密和认证：

- 设置加密算法为“AES-128”。

- 设置认证算法为“SHA1”。

4、配置网络：

- 指定要通过VPN隧道传输的内部网络。

- 确保Juniper设备上的隧道接口地址与Zyxel设备上的本地网络地址不冲突。

5、保存并测试连接：

- 保存配置并尝试建立VPN连接。

- 使用ping或traceroute测试VPN隧道的连通性。

确保在配置过程中，两个设备的时钟是同步的，并且所有的地址和密钥都正确无误，检查防火墙规则以确保VPN流量不被阻止，如果遇到连接问题，检查日志文件以诊断问题。
