Sygate ADSL user installation Configuration

Note: Only Versions later than Sygate 4.0 can correctly support ADSL. Otherwise, some websites of the client may fail to be accessed. This article takes Sygate 4.0 Office Network as an example to describe, the more common Sygate 4.0 Home network does not change much.

Using Sygate to achieve shared Internet access for LAN users can adopt two solutions: single Nic and dual Nic. The single Nic solution is suitable for clients with fewer (less than 10 shared Internet connections), and dual NICs are suitable for larger LAN shared Internet access. If a single network card is used to provide Internet sharing service for a large LAN, a single network card simultaneously processes ADSL signals, lan signals, and shared Internet signals will affect the system's Internet speed.

Single NIC (Single NIC) Sharing PPPoE hardware connection Configuration

The configuration diagram is as follows:

Dual NIC sharing PPPoE hardware connection settings

The configuration diagram is as follows:

Whether using a single or dual Nic, the configuration of the Sygate server is the same under ADSL. The configuration of the Sygate server software is described below.

Open the Sygate server console, as shown in. Click the Advanced button to enable the extension settings and set the server.

The left side of this window shows the network connection status, the upper half of the bandwidth and data volume used by the internal computer for Internet access, and the lower half of the server Internet connection status. Click the Configuration button to enter the Sygate settings window, as shown in.

The Sygate Configuration window contains many configuration items. The following describes their settings.

• Basic settings

  Use Single NIC Mode Settings: Use the single Nic mode. This mode is used for the host to use the ADSL leased line mode, and only one Nic has the internal network parameters and Internet leased line parameters set at the same time, after selecting this mode, enter the internal network IP address of the network adapter, which is used by other computers on the LAN to share the internet.
  Direct Internet/ISP Connection (External Connection in Home): Which interface (Dial-Up, leased line Nic, etc.) on the server is used by Sygate to connect to the Internet to provide shared Internet access? You can add it according to your actual situation, delete the Internet interface provided to Sygate. The Office version can integrate the bandwidth of up to four Internet interfaces for the client to expand the network bandwidth.
  Dialup Entry Settings, then, the Sygate server can automatically connect to the ISP Based on the configured Internet interface.
  Auto Disconnect Settings: Automatic disconnection settings. When no data passes through the Internet interface for the set time, Sygate can automatically close the Internet connection. If you do not want to use automatic disconnection, select Never auto disconnect.
  Connect additional line if current average traffic exceeds
  (Only available in Office versions): When you integrate multiple Internet interfaces, once the Internet accesses the total data volume per second at a certain time point, it exceeds the rate bandwidth set here, then, Sygate automatically connects to other configured Internet interfaces to meet client requirements.
  Local Network Connections (the Home version is called Internal Connection ):Set the interface on the server to connect to the internal LAN to provide shared Internet access for LAN users.
  Bridge Settings:Bridge settings are used to connect to a LAN of multiple different network segments to provide services. You can enter the IP address of the bridge connected to these lan. Generally, we rarely use this configuration.
  Options: System function settings, including [Auto-detect newer version]: automatically checks whether a new version of Sygate exists. [Enable Internet Sharing]: Enable Internet Sharing service, [Enable Address Server (DHCP)] open the DHCP Dynamic IP Address service built in Sygate. After opening it, the client can automatically obtain the IP address, gateway, DNS, and other parameters that need to be configured by setting the IP address to automatic, network management workload can be reduced. Click the Advanced button to set parameters of the DHCP service. [Enable Access log] After selecting it, the Sygate log function is enabled. Click the ActivityLog of the tool bar to view detailed records of the client's Access to the Internet, such as the URL, IP address, and data type, easy to manage. Note that you need to install the Microsoft ODBC database dynamic program to use the log function. [Enable Bandwidth Management] This is the Bandwidth Management function used by some clients in the Office version. You can limit the network Bandwidth used by the client to prevent a large number of downloads from other users from causing slow Internet access for other users.
  

• ADSL virtual dialing settings

WinPoET/RasPPPoE virtual dialing
* *** The configuration for using WinPoET/RasPPPoE virtual dialing is exactly the same as that for using 56K dialing. After WinPoET/RasPPPoE virtual dialing works properly, after the Sygate hypervisor is started, the dial-up file is automatically located.Direct Internet/ISP Connection (External Connection in Home) External ConnectionSelect (ADD) the dial-up file. If you want Sygate to automatically dial, go to [EDIT] to modify the file, select the dial-up file, and enter the user name and password.Local Network Connections (the Home version is called Internal Connection) Internal ConnectionSelect the NIC to connect to the LAN. If it is a single Nic solution, select this Nic. The dual Nic solution is required. Be sure not to select the NIC to connect to the adsl modem. You must select the NIC to connect to the HUB.

Enternet 300/500 virtual dialing
* *** To use the Enternet virtual dialing program, we needDirect Internet/ISP Connection (External Connection in Home) External ConnectionSelect (ADD) the network Adapter (PPPoE Adapter) That is virtualized by Enternet in the settings. Because it is a simulated lan network Adapter, automatic dial-up and other functions of Sygate will no longer be available.Local Network Connections (the Home version is called Internal Connection) Internal ConnectionSelect the network card that connects to the LAN. If it is a single network card solution, select the physical network card that already exists. The dual network card solution must not be selected as the network card that connects to the adsl modem, be sure to select the one to connect to the HUB.

For users who use the USB interface adsl modem, they only need to consider the NIC virtualized by the usb adsl modem driver as the second Nic connected to the adsl modem in the dual Nic solution, the standard Nic connected to the local area network must be set as the NIC of the internal HUB.

Advanced Settings
Click the Advanced button in the Configuration window to go to the Advanced settings of Sygate,

[Address Server] Here, we can set the DHCP Dynamic IP automatic service function. Automatically Determine the IP range enables Sygate to Automatically Determine the IP Address allocation range, use the following assigned IP range to manually specify the IP address range.
[Domain Name Server (DNS)] You can manually specify the Domain Name Server search sequence of the ISP. You do not need to set the sequence here unless the ISP requires or is often unable to access the Domain Name.
[Connection time out] set the time for the client to access a website. If no data is transmitted, Sygate closes the Connection and resources are reclaimed.
[PPPoE Configuration] when using PPPoE virtual dialing, faults may occur due to conflicts between LAN signals and PPPoE signals, the MTU parameter, which is one of the important symbols for distinguishing management signal categories in the network, can solve this problem. When some websites cannot be accessed, or the access speed is very slow, when sending emails with attachments is difficult, the MTU value here is often reduced or unexpected.

Other Sygate Management Functions
[Firewall] firewall function. The Sygate Office version has built-in Sygate personal Firewall, which can protect your network security. It can monitor program access to the internet requests on the host and prevent Trojans, click the FireWall button in the toolbar to open the FireWall settings window, which is divided into several security level settings, such as high mediem low off.
[Bandwidth management] The client uses Bandwidth management, which is also a feature exclusive to the Sygate Office version. When Bandwidth management is enabled in the Configuration window, we can go to the Tools menu for management.

In bandwidth management, we can see the Basic settings of the System in two sets and the Group user Group.
SystemIn Maximum Bandwidth of server, we can specify that the Sygate server provides a Maximum of Internet Bandwidth shared by users. The value range is 6 KB/s to 6000 KB/s. After the Bottleneck Prevention is selected, Sygate can dynamically allocate a certain amount of bandwidth based on the user's usage history. For example, the number of points that are frequently browsed on the web page and the number of points that are frequently downloaded.
Application Priority allows you to set the bandwidth available for various Internet applications (such as browsers and emails. NewAPP can add new types of programs, and ALL programs can only use the set bandwidth. If you do not use groups, this setting manages the access bandwidth of ALL users.
GroupUsers can be grouped. After grouping, some users can be provided with more bandwidth, and some users can be provided with less convenient management, so as to adapt to the work characteristics of users and improve bandwidth efficiency.

Client Access Control
Click the Permission button in the toolbar to open the client access control settings. Black/White management and blacklist management are used. Therefore, users in the blacklist are restricted by access and managed by whitelist. Only users in the whitelist can access the authorization function, other users not in the list cannot access each other.
