The USG firewall configures SSL VPN file shares
The main function of file sharing is to share the resources of different system servers (such as Windows systems that support SMB protocol, Linux systems that support NFS protocol) in the form of web pages. Before the configuration to ensure that the license file has been loaded, the USG can access the internal network resources.
Configuration steps:
1. In the USG to create a virtual gateway, external network users through this virtual gateway to access the enterprise network resources.
2. Configure the DNS server address and domain name of the internal network so that users can access the virtual gateway's service through the domain name.
3. Configure file sharing, add file type resources for SMB type and NFS type.
4. Configure the authentication and authorization function.

USG firewall configure SSL VPN network extension
USG Firewall Configure SSL VPN to configure network extensions Network expansion refers to the user on the local PC to install the USG network extension client, generate a virtual network card, the user through the virtual network card and enterprise intranet for SSL data communication. Before the configuration to ensure that the license file has been loaded, the USG can access the internal network resources. Configuration ideas: 1. In the USG to create a virtual gateway, external network users through this virtual gateway to access the enterprise network resources. The IP address of the virtual gateway is the public address of the egress. 2. Configure the DNS server address and domain name of the internal network so that users can access the virtual gateway's service through the domain name. 3. Configure the network extension function, assign IP addresses to the external network users and add the intranet resources that the external network users can access. 4. Configure the authentication mode as a certificate challenge (secondary authentication mode: VPNDB) and configure the authentication mode as VPNDB. 5. Add a VPNDB user. VPNDB user name that is the name of the client certificate, VPNDB password is the external network user login virtual gateway need to enter the password. 6. Configure the virtual gateway source IP policy. 7. Install the client certificate for the CA certificate on the PC side where you want to access the virtual gateway.

The USG firewall configures the SSL VPN port for forwarding
The USG firewall configures the SSL VPN port for forwarding The port forwarding service is a secure application that provides TCP-based applications and is a non-Web application. Port forwarding controls user access at the application level to control the availability of services for various applications. Before the configuration to ensure that the license file has been loaded, the USG can access the internal network resources. Configuration step: 1. In the USG to create a virtual gateway, external network users through this virtual gateway to access the enterprise network resources. 2. Configure the DNS server address and domain name of the internal network so that users can access the virtual gateway's service through the domain name. 3. Configure the port forwarding function. 4. Configure the server to add users who need access to the relevant groups. 5. Configure the authentication and authorization function on the firewall. 6. Configure Group Policy to allow group users to access the associated server. 7. Configure the user destination IP policy to restrict users from accessing other intranet resources.

Configuring an SSL VPN virtual gateway on the firewall
Configuring virtual gateways on the USG 1. system-view 2. v-gateway v-gateway-name { ip-address | interface interface-type interface-number } [ port port-number ] { private [ domain-name ] | public domain-name } //Create a virtual gateway. A private gateway is in exclusive mode, and a public gateway is in shared mode. 3. quit 4. v-gateway v-gateway-name ip address ip-address [ port port-number ] //Assign an IP address and a port number to the virtual gateway. Exclusive virtual gateway: v-gateway v-gateway-name ip address ip-address [ port port-number ] command: If the entered IP address is the existing IP address of the virtual gateway, this command changes the virtual gateway port number. If the entered IP address is not the IP address of the virtual gateway, this command adds the virtual gateway IP address. The undo v-gateway v-gateway-name ip address ip-address command deletes the IP address of the virtual gateway. The v-gateway v-gateway-name ip address old-ip-address new-ip-address [ port port-number ] command changes the IP address of the virtual gateway. Shared virtual gateway: v-gateway v-gateway-name ip address ip-address [ port port-number ] command: If the entered IP address is the existing IP address of the virtual gateway, this command changes the virtual gateway port number. If the entered IP address is not the IP address of the virtual gateway, this command changes the virtual gateway IP address. You cannot run the undo v-gateway ip address command to delete the IP address of the virtual gateway. The v-gateway v-gateway-name ip address old-ip-address new-ip-address [ port port-number ] command changes the IP address of the virtual gateway. If a port bound to the IP address of the virtual gateway is used for other purposes (such as web management or SSH login), the port cannot be configured as the port of the virtual gateway. 5. v-gateway v-gateway-name interface interface-type interface-number [ port port-number ] //Modify the virtual gateway interface. 6. v-gateway v-gateway-name domain domain-name //Modify the virtual gateway domain name. 7. v-gateway v-gateway-name http-redirect enable //Configure the HTTP redirection function of the virtual gateway. 8. v-gateway v-gateway-name max-user max-user //Modify the maximum number of virtual gateway users. Its default value is 1. 9. v-gateway v-gateway-name cur-max-user cur-max-user //Modify the maximum number of concurrent users of the virtual gateway. 10. v-gateway v-gateway-name max-resource max-resource //Modify the maximum number of resources on the virtual gateway. Its default value is 1.

Working principle of SSL VPN on the USG
Working principle of Secure Sockets Layer (SSL) VPN on the USG 1. Concept SSL is a security protocol that provides security connections for application layer protocols that are based on TCP. The SSL protocol is widely applied in fields such as e-commerce and e-banking to ensure security for data transmitted over the network. SSL can implement connection privacy, identity authentication, and connection reliability. 2. SSL The SSL protocol is composed of two layers. a. Lower-layer protocol SSL record protocol The SSL record protocol divides upper-layer data into records, compresses and calculates the records, appends message authentication codes (MACs) to the records, encrypts the records, and then transmits the records to the peer party. b. Upper-layer protocols (1) SSL handshake protocol: The client and server establish a session through the handshake protocol. The session contains a group of parameters, including the session ID, certificate of the peer party, encryption algorithm list (including the key exchange algorithm, data encryption algorithm, and MAC algorithm), compression algorithm, and primary key. The SSL session can be shared by multiple connections to reduce the session negotiation overhead. (2) SSL change cipher spec protocol: The client and server notify the recipient through the SSL change cipher spec protocol that subsequent packets are protected and transmitted based on the newly negotiated encryption algorithm list and key. (3) SSL alert protocol: used by a party to report alarm information to the other party. The message carries the alarm severity and description. 3. SSL VPN provides four types of services: a. Web proxy The web proxy allows users to access web servers on the internal network through the USG and provides HTTP-based web services for users. b. Network extension After a user installs the network extension client of the USG on the local PC, a virtual NIC is generated. The user can then conduct SSL data communication with the intranet through this virtual NIC. c. Port forwarding As a non-web application mode, port forwarding provides security access for TCP-based applications. In port forwarding, user access is controlled at the application level. d. File sharing File sharing involves providing shared resources in Windows systems that support different server protocols such as the System Management Board (SMB) protocol, or Linux systems that support the Network File System (NFS) protocol as web pages to users.
