Connection of bintec 4Ge-LE™
In principle the
bintec 4Ge-LE™ runs as a DHCP Client and receives from the gateway the
names and the PIN for the SIM card via the option 43 (Vendor specific). The device uses this data to establish a LTE
(UMTS/GPRS) connection and provides the received IP address, the gateway and the DNS server as DHCP server on an
Ethernet connection of
be.IP™ tagged with VLAN 463. This means that the
be.IP™ is on the actual interface DHCP server on a virtual port with
VLAN 463 against DHCP client!
In the example, en1-4 (the blue DMZ/WAN Port) is used, although this can be configured in the same way on
any separate port.
The interfaces are now adjusted/created in the first step.
-
Enter in the menu
LAN->IP
Configuration->Interfaces-> en1-4
.
Proceed as follows:
-
Leave the Interface
Mode settings as
Untagged
. The interface is not
assigned for a specific purpose.
-
Leave the
Security Policy
settings as
Trusted
. All IP packets are
allowed through except for those which are explicitly prohibited.
-
Enter the
IP Address / Netmask of
the virtual interface, here e.g.
192.168.43.41
und
255.255.255.252
.
-
Click
OK to confirm your entries.
In the next step, create a new interface.
-
Go to
LAN->IP
Configuration->Interfaces->New.
Proceed as follows:
-
Under
Based on Ethernet
Interface select the virtual interface
en1-4
.
-
Set the
Interface Mode to
Tagged (VLAN)
.
-
Assign a VLAN to the interface. To do this, enter the
VLAN ID
463
.
-
For
Security
Policy, select
Untrusted
.
-
Select the
Address Mode
DHCP
. An IP address is
assigned to the interface dynamically via DHCP.
-
Under
DHCP Metric select the
priority of the route, which is
5
in our example.
-
Click
OK to confirm your
entries.
The netmask for en1-4 was selected with /30 so that only one IP range of 2 addresses is needed:
-
be.IP™ (192.168.43.41)
-
bintec 4Ge-LE™ (192.168.43.42)
Network address is therefore 192.168.43.40, broadcast address is 192.168.43.43.
The complete configuration now looks like this:
Now for the virtual interface
en1-4-1
must be enabled as IPv4 WAN interface
NAT.
-
Go to
Network->NAT->NAT
Interfaces.
-
For the
Interface
LAN_EN1-4-1
enable the options
NAT active
and
Silent Deny
.
-
Click
OK to confirm your entries.
The last configuration step is setting up the DHCP server with the corresponding DHCP option
43
on the interface
en1-4
. For security reasons, a static connection of the IP address to
the MAC address of the
bintec 4Ge-LE™ is carried out so that only this received an IP address
(and only this is sent the option 43 with the PIN included).
To activate the device as DHCP server, the IP address pool must first be defined.
-
To do so, go to the
Local
Services->DHCP
Server->IP Pool
Configuration->New
menu.
-
Under
IP Pool Name enter any
description, here e.g.
bintec 4Ge-LE
.
-
Under
IP Address Range enter the
IP address of the IP address pool, here
192.168.43.42 - 192.168.43.42
.
-
Confirm with
OK.
Under
Local
Services->DHCP
Server->DHCP
Configuration->New
you can now set up the DHCP pool.
Proceed as follows:
-
Select Interface
en1-4
.
-
Under IP Pool Name
select the configured IP pool name
bintec 4Ge-LE
.
-
Click
Advanced Settings.
-
In the Vendor Specific
Information (DHCP Option 43) field, click on the
Add Vendor String button.
-
Under
Select vendor select
-bintec-
.
-
Enter the
APN (Access Point Name) of the
provider of your SIM card, here e.g.
internet.telekom
.
-
Enter the
PIN of the SIM card, e.g.
1234
.
-
Click Apply.
The last step involves establishing the static connection of the IP Address to the MAC address.
-
Go to the
Local
Services->DHCP
Server->IP/MAC
Binding menu.
-
Enable the
Static Binding
option.
-
Confirm with OK.
With this configuration only the
bintec 4Ge-LE™ on the interface
en1-4
receives an IP address with the SIM card PIN included in option
43.
This concludes the configuration. Store the configuration using
Save configuration above the
menu bar
