General settings
Before describing the procedure for entering the parameters, let's make a small summary of how a network works.
• Remote access to the web server is via the Internet.
• Each Internet node (host) is uniquely identified by a number (32-bit IPv4, 128-bit IPv6), commonly called IP address.
Example of IPv4 address: 190.230.140.122
• To make the identification of Internet nodes more easy, it was created a system for associating an alphanumeric string to the
IP addresses: DNS (Domain Name System)
For example:
IP Address: 213.178.196.136
DNS Name: www.vimar.com
• Obviously, for access to an IP node, you must know the address or DNS name associated with it
• Assigning an IP address to a host can be:
- static: the address is assigned permanently
- dynamic: the address assigned is not always the same.
A typical example is provided by Internet Service Providers addressing referenced by private users for internet access. The address is typically
assigned with each connection (in some cases can also be edited within the same session)
• To enable access to Internet nodes whose address is dynamically assigned, have been developed services that help
create an association between dynamic DNS name (assigned to a user) and IP address. These services are called Dynamic DNS (DDNS
Dynamic DNS)
• Many of the ADSL routers on the market today have native DDNS services support for one or more providers.
The router sends the updated IP address to the DDNS after it's been assigned or after the Internet Service Provider has changed the IP
address.
• Typically, configuring a dynamic DNS on a router that supports this technology involves the following steps:
1. Creating an account on the dynamic DNS provider chosen (e.g. DynDNS.org)
2. From the Internet configuration menu of the router select the option for Dynamic DNS (Dynamic DNS, DDNS)
3. Select the Dynamic DNS provider among those managed by the router (typically via a drop down menu)
4. Type the data provided by dynamic DNS providers in the appropriate fields.
• For remote access to the Web Server, the following settings are required:
- Configuration of the IP address of the Web Server in the LAN
- Configuration of the NAT on the router
- Check the opening of the https port on the ADSL router (port 443) and, if remote management of the configuration and diagnostics of
the By-alarm system via the By-alarm manager software is envisaged, open also the router port that will be mapped in the port used
by the By-alarm manager software to access the Web Server.
NOTE: If the port 443 of the external interface of the router is already being used by other services, you can use a different port (if not
used) but this must be linked to port 443 on the web server (this cannot be changed) by creating a port forwarding rule in the router.
IMPORTANT: For safety reasons, configure the router so that only ports 443 (HTTPS) of the web server and the port defined for a
remote configuration of the By-alarm control panel (if present in the system) are accessible from outside the LAN.
- If you use dynamic DNS systems, make the relevant configurations
• The web server has a default configuration of that address.
If you need to change that address, access the web server using the default address and change it from the configuration pages.
This configuration, to be performed on the router, is need to tell the router that the remote requests on the https port should be addressed
to the same LAN address identifying the web server. For this setting, refer to the instruction manual of your router.
• The web server uses the HTTPS protocol to increase security of the remote connection between the user and the web server.
The protocol uses a specific port (443) to be opened on the router
• The web server can be used even if the ISP assigns a dynamic IP address.
• The web server runs natively the dynamic DNS service offered by DynDNS.
In this case, carry out the appropriate settings on the pages of the web server.
If you use a router that manages the dynamic DNS service chosen by the user natively, set the necessary configurations on the router.
