Chapter 9

Web Interface

WinRoute contains a special Web server that can be used for several purposes, such as an interface for user authentication and setting of certain user account parameters. This Web server is available over SSL or using standard HTTP with no encryption (both versions include identical pages).

Use the following URL (’server’ refers to the name or IP of the WinRoute host, 4080 represents a standard HTTP interface port) to open the unsecured version of the web interface.

https://server:4081/

To use the encrypted version specify the HTTPS protocol and number of the port of the encrypted Web interface (default is 4081) — e.g.

https://server:4081/

Note: This chapter addresses settings of web interface parameters and user preferences (available to all users). Statistics viewed in the web interface (available only to users possessing appropriate rights) are addressed in chapter 19.

9.1 Web Interface Parameters Conﬁguration

To deﬁne basic WinRoute Web interface parameters go to the Web Interface folder in Conﬁguration → Advanced Options.

Note: The top part of the Web Interface → SSL-VPNtab is used for Kerio SSL-VPNsettings. For detailed information on this component, see chapter 22.

Enable Kerio SSL-VPN server

This option enables/disables the Kerio Clientless SSL-VPNinterface. For details, refer to chapter 22.

Enable Web Interface (HTTP)

Use this option to open the unsecured version (HTTP) of the Web interface The default port for this unsecured interface is 4080.

Note: The main disadvantage of usage of the unsecured web interface is that the network traﬃc may be tapped and user login data might be misused. Therefore, the secured web interface shall be always preferred.
