   Figure 3: IPsec VPN Page

2. At the right corner of the page, select Create VPN > Remote Access > Juniper Secure Connect to create the IPsec VPN setting for Juniper Secure Connect.

   The following warning message appears:

   Figure 4: Warning Message To Generate And Bind Self-signed Certificate

   As mentioned in the warning message, create a self-signed certificate and bind the certificate to the SRX Series Firewall. For more information, see Preparing Juniper Secure Connect Configuration.

   For detailed information about creating a remote access VPN, see Create a Remote Access VPN—Juniper Secure Connect.

3. Again navigate to Network > VPN > IPsec VPN and at the right corner of the page, select Create VPN > Remote Access > Juniper Secure Connect to create the IPsec VPN setting for Juniper Secure Connect. The Create Remote Access (Juniper Secure Connect) page appears. Figure 5 shows an example to create remote access VPN.

   Figure 5: Create VPN - Remote Access

   Figure 6 shows an example of the create remote access page with pre-shared key authentication method.

   Figure 6: Create Remote Access Page For Pre-shared Key Authentication Method

1. Enter the name for the Remote Access Connection (this is, the name that will be displayed on the End Users Realm Name in Juniper Secure Connect application) and a description.

2. The routing mode is set to Traffic Selector (Auto Route Insertion) by default.

3. Select the authentication method. For this example, let’s select Pre-shared Key from the drop-down list.

4. Select Yes to create the firewall policy automatically using the Auto-create Firewall Policy option.

Figure 8: Remote User Page

Figure 8 shows an example of the Remote User page.

Configure the remote user client by selecting the options on the Remote User page and then clicking OK :

Table 1 summarizes the remote user settings options.

Figure 9 shows an example of the local gateway configuration settings.

Figure 9: Local Gateway Configuration

1. If you enable Gateway is behind NAT, a text box appears. In the text box, enter the NAT IP address. We support only IPv4 addresses. NAT address is the external address.

2. Enter a IKE ID in user@hostname.com format. For example, abc@xyz.com.

3. In the External Interface field, select the IP address for the clients to connect. You must enter this same IP address (in this example: https://12.12.12.12/) for the Gateway Address field in the Juniper Secure Connect application.

   If you enable Gateway is behind NAT, then the NAT IP address becomes the gateway address.

4. From the Tunnel Interface drop-down list, select an interface to bind it to the route-based VPN. Alternatively click Add. If you click Add, the Create Tunnel Interface page appears.

   Figure 10 shows an example of the Create Tunnel Interface page.

   Figure 10: Create Tunnel Interface Page

   The next available ST0 logical interface number is displayed in the Interface Unit field and you can enter a description for this interface. Select the zone to add this tunnel interface to. If Auto-create Firewall Policy (in Create Remote Access page) is set to Yes, the firewall policy uses this zone. Click OK.

5. Enter the preshared key in ASCII format. We do not support hexadecimal format for remote-access VPN.

6. From the User Authentication drop-down list, select an existing access profile or click Add to create a new access profile. If you click Add, the Create Access Profile page appears.

   Figure 11 shows an example of the Create Access Profile page.

   Figure 11: Create Access Profile Page

   Enter the access profile name. From the Address Assignment drop-down list, select an address pool or click Create Address Pool. If you click Create Address Pool, the Create Address Pool page appears.

   Figure 12 shows an example of the Create Address Pool page.

   Figure 12: Create Address Pool Page

   • Enter the details for the local IP pool that is in the VPN policy for the clients. Enter a name for the IP address pool.

   • Enter the network address that you use for the address assignment.

   • Enter your DNS server address. Enter WINS server details, if required. Now click the add icon (+) to create the address range to assign IP addresses to the clients.

   • Enter the name, and the lower and higher limits. After entering the details, click OK.

   Select the Local check box to create local authentication user, where all the authentication details are stored on the SRX Series Firewalls. If you click the add icon (+), the Create Local Authentication User window appears.

   Figure 13 shows an example Create Local Authentication User page.

   Figure 13: Create Local Authentication User Page

   Enter a username and password, and then click OK. Click OK again to complete the access profile configuration.

7. From the SSL VPN Profile drop-down list, select an existing profile or click Add to create a new SSL VPN profile. If you click Add, the Add SSL VPN Profile page appears.

   Figure 14 shows an example of the Add SSL VPN Profile page.

   Figure 14: Add SSL VPN Profile Page

   On the Add SSL VPN Profile page, you can configure the SSL VPN profile. Enter the SSL VPN profile name in the Name field, and enable logging using the toggle, if required. In the SSL Termination Profile field, select the SSL termination profile from the drop-down list. SSL termination is a process where the SRX Series Firewalls acts as an SSL proxy server, and terminates the SSL session from the client. If you want to create a new SSL termination profile, click Add. The Create SSL Termination Profile page appears.

   Figure 15 shows an example of the Create SSL Termination Profile page.

   Figure 15: Create SSL Termination Profile Page

   • Enter the name for the SSL termination profile and select the server certificate that you use for the SSL termination on the SRX Series Firewalls. Click Add to add a new server certificate or click Import to import the server certificate. The server certificate is a local certificate identifier. Server certificates are used to authenticate the identity of a server.

   • Click OK.

8. The Source NAT Traffic option is enabled by default. When Source NAT Traffic is enabled, all traffic from the Juniper Secure Connect application is NATed to the selected interface by default. Click the toggle button to disable the Source NAT Traffic option. If the option is disabled, you must ensure that you have a route from your network pointing to the SRX Series Firewalls for handling the return traffic correctly.

9. Under Protected Networks, click add icon (+) to select the networks that the Juniper Secure Connect application can connect to.

   Figure 16 shows an example of the Create Protected Networks page.

   Figure 16: Create Protected Networks Page

   By default, any network 0.0.0.0/0 is allowed. If you configure a specific network, split tunneling for Juniper Secure Connect application is enabled. If you retain the default value, you can restrict access to your defined networks by adjusting the firewall policy from the client network. Click OK, and the selected networks are now in the list of protected networks. Click OK to complete the local gateway configuration.

   Figure 17 shows an example of successful completion of remote access configuration with remote user and local gateway.

   Figure 17: Complete Remote Access Configuration

   IKE Settings and IPsec Settings are advanced options. J-Web is already configured with default values for the IKE and IPsec parameters. It is not mandatory to configure these settings.

Figure 18 highlights the URL that remote user must enter in the Gateway address field in Juniper Secure Connect application to establish remote access connection.

Figure 18: Commit Remote Access Configuration

1. Click Save to complete the Juniper Secure Connect VPN configuration and associated policy if you have selected the auto policy creation option.

2. Click the highlighted Commit button (at the top right of the page next to Feedback Button) to commit the configuration.
