From ISP admin

Routered nets

To be able to connect the clients to the router, it is necessary to have defined IP ranges.

In the section Routed networks on the router (at the bottom of the screen) are displayed readout networks that route on the router. These networks can be added to the system just like the so called "IP addresses for cable modems", "IP addresses for cable users", "IP addresses for the installation of modems and users", "IP addresses for the WIFI users", "IP addresses for IP phones" and "IP addresses for the hardware devices".

From the specified IP address for the WIFI users the free IP addresses will be offering themselves automatically when entering a new Internet service. IP addresses for hardware devices , however, will be not offered and remain reserved only for devices (gateways, servers, etc.).

The system monitors the IP collision. So it is not possible that more clients would be sharing the same address. This way you can quite easily fill gaps in the range (free address blocks). So, if you have the automatic allocation of IP addresses set, the system will start from the first free IP and continue in offering other free IP addresses till it hits the busy one, in which case it skips it and will continue in offering other free ones from the spaces again.

The ISPadmin system also allows Manual assignment of IP addresses. This feature can be useful if you already have clients added or wish to enter the IP address manually. . You can change the settings in Settings / System settings / General, where you will adjust the ip_set_type item. Once you will have manually entered all the IP addresses, you can go back on automatic allocation, which will allow you to fill holes created in scope.

An overview of all allocated IP addresses will then be displayed in the tab Statistics / IP ranges, where everything is neatly presented.

Certain rules of Firewall are applied on the defined range. Firstly, those addresses which are already allocated to clients will be allowed in the given range and on the rest of IP from this network (range) the DROP will be at the end applied. This means that those clients who are entered into the system will function normally and the rest will be forbidden. This connection eliminates the stowaways - clients. This default behavior can be overridden by canceling the box in router Apply firewall rules.

The specified IP ranges

- This network is not manually configured on the router and as such it could not be retrieved (it is only written in ISPadmin)

- List of allocated IP addresses in a given range. A new screen with a graphical overview of the assigned IP addresses to clients and facilities will show up.

- Editing already defined range, the screen is identical to the Addition of a new range of networks.

- Delete a network from a range of IP addresses for clientsDelete a network from a range of IP addresses for clients / devices. Previously allocated IP addresses are retained.

It is necessary to have the IP ranges for WIFI clients defined, so that it is then possible to connect clients to the router. Overviews of defined networks for different groups:

• IP addresses for cable modems
• IP addresses for cable users
• IP addresses for the installation of modems and users
• IP address for WiFi users
• IP addresses for IP phones
• IP addresses for hardware devices

Routed networks on the router

- Changing of network parameters. This menu is identical to the screen Add a new range of network, see below.

Setting up of everything that is supposed to be read perform in the menuOptions / System settings / Mikrotik item reading_dynamic_routes. Here are displayed all readout routed networks that route on this router. It actually copies the menu IP/Addresses in Mikrotik. The system automatically reads them through SSH or API. If there is an icon of editing displayed at the end of the line, this range can be defined as network for clients, modems or other hardware devices.

So if you add this way selected IP ranges as managed networks on the router, free IP addresses from these ranges will be offering themselves in setting up the Internet service. Without setting up these IP ranges it will not be possible to enter the clients!

If the line with routed networks tinged with gray color it is not possible to manipulate with this network in any way, because it figures as one of the specified IP ranges. If you need to reassign IP ranges between routed networks, it is necessary to remove the assigned IP ranges with the button (previously allocated IP addresses are retained).Then the line will be tinged with white colour and the button of edits will appear.

It is not possible to cancel the routed networks, because the shaping is done on the basis of them.

Adding a new range of network

Network / Mask

New range of network. Enter the mask bitwise by the prefix.

Default router

Gateway IP address for a given range, which is usually the IP of the router.

Description

Personal description and knowledge to the new range.

Allocate the address from the number

The allocation of new IP addresses only from this specified address.

The dynamic range of the DHCP

Settings for Linux routers. For MikroTiK irrelevant (there must be an active DHCP Server precisely on MikroTiK). Clients are allocated with an IP address from this range regardless of the specified MAC address. Incorrectly specified IP addresses can cause malfunction of DHCP.

Type of the IP range

Type of IP addresses. Private or Public.

IP range is for

Defining a group for which the generated range specified.

You can choose from the options: Modems, Users, Installation modems, WiFi / LAN, IP phones, hardware devices.

Dedicated IP addresses

Addresses that we do not want to use for allocating addresses to clients such as Gateway, spec. addresses of scale.
