Configuring HTTP Proxy Servers

The HTTP Proxy Servers table lets you configure up to 10 HTTP Proxy servers. Once configured, you can configure HTTP Locations for the HTTP Proxy Server (see Configuring HTTP Locations).

The following procedure describes how to configure HTTP Proxy Servers through the Web interface. You can also configure it through ini file [HTTPServer] or CLI (configure network > http-proxy > http-server).

➢ To configure an HTTP Proxy Server:
1. Enable the HTTP Proxy application, as described in Enabling the HTTP Proxy Application.
2. Open the HTTP Proxy Server table (Setup menu > IP Network tab > HTTP Proxy folder > HTTP Proxy Servers).
3. Click New; the following dialog box appears:

4. Configure an HTTP Proxy server according to the parameters described in the table below.
5. Click Apply, and then save your settings to flash memory.

HTTP Proxy Servers Table Parameter Descriptions

Parameter

Description

'Index'

[Index]

Defines an index number for the new table row.

Note:

■ Each row must be configured with a unique index.
■ The parameter is mandatory.

'Name'

name

[ServiceName]

Defines a descriptive name, which is used when associating the row in other tables.

The valid value is a string of up to 40 characters. By default, no value is defined.

Note:

■ Configure each row with a unique name.
■ The parameter is mandatory.
■ The parameter value cannot contain a forward slash (/).

'Domain Name'

domain-name

[DomainName]

Defines a domain name (FQDN). This is configured only when multiple DNS domains share the same IP address.

Note: The NGINX directive for this parameter is "server_name".

'Listening Interface'

listening-int

[ListeningInterface]

Assigns an IP Interface to the HTTP Proxy service. To configure IP Interfaces, see Configuring IP Network Interfaces.

Note:

■ The parameter is mandatory.
■ The NGINX directive for this parameter is " listen ip".

'HTTP Listening Port'

http-port

[HTTPListeningPort]

Defines the HTTP listening port, which is the local port for incoming packets for the HTTP service.

Note:

■ The port number must not conflict with the ports used for the Web interface, which is usually 80 for HTTP and 443 for HTTPS.
■ You must configure at least one port (HTTP or HTTPS port).
■ The NGINX directive for this parameter is "listen ip:port".

'HTTPS Listening Port'

https-port

[HTTPSListeningPort]

Defines the HTTPS listening port, which is the local port for incoming packets for the HTTP service.

Note:

■ The port number must not conflict with the ports used for the Web interface, which is usually 80 for HTTP and 443 for HTTPS.
■ You must configure at least one port (HTTP or HTTPS port).
■ The NGINX directive for this parameter is "listen ip:port ssl".

'TLS Context'

tls-context

[TLSContext]

Assigns a TLS Context (TLS configuration). This is required if you have specified an HTTPS listening port (see the 'HTTPS Listening Port' parameter above). To configure TLS Contexts, see Configuring TLS Certificate Contexts.

Note: The NGINX directives for this parameter is "tls-context", "ssl_certificate", "ssl_certificate_key", "ssl_ciphers", "ssl_protocols", and "ssl_password_file".

'Bind To Device'

bind-to-device

[BindToDevice]

Enables the NGINX to bind the HTTP Proxy interface to a specific device network interface.

■ [0] Disable
■ [1] Enable (default)

'Verify Client Certificate'

verify-client-cert

[VerifyCertificate]

Enables the verification of the client TLS certificate, where the client is the device or user that issues the HTTPS request.

■ [0] No = (Default) No certificate verification is done.
■ [1] Yes = The device verifies the authentication of the certificate received from the HTTPS client. The device authenticates the certificate against the trusted root certificate store associated with the assigned TLS Context (see 'TLS Context' parameter above) and if ok, allows communication with the HTTPS client. If authentication fails, the device denies communication (i.e., handshake fails). The device can also authenticate the certificate by querying with an Online Certificate Status Protocol (OCSP) server whether the certificate has been revoked. This is also configured for the associated TLS Context.

'Additional Directive Set'

directive-set

[AdditionalDirectiveSet]

Assigns an NGINX Directive Set for the HTTP service. To configure HTTP Directive Sets, see Configuring HTTP Directive Sets.
