Services

In the service settings, you configure the DHCP service, DNS forwarding, VRRP, and other related parameters.

DHCP Service

The Dynamic Host Configuration Protocol (DHCP) is a communication protocol in network technology. It enables the assignment of the network configuration to clients through a server. In this way, devices in the network can be assigned IP addresses dynamically. You can access this service under Services > DHCP Service.

Name	Description	Default
Enable DHCP	Click to enable DHCP	Enabled
IP Pool Starting Address	Set start IP address of the DHCP pool	192.168.2.2
IP Pool Ending Address	Set end IP address of the DHCP pool	192.168.2.100
Lease	Set valid lease time for the IP address received from the DHCP server	60 minutes
DNS	Set DNS server (click via Edit)	192.168.2.1
Windows Name Server	Set WINS	Blank
Static DHCP (a maximum of 20 IP addresses can be set)
MAC Address	Set MAC address of a designated IP address	Blank
IP Address	Set static IP address	192.168.2.2
Host	Set hostname	Blank

DNS

Up to two DNS servers can be entered here if the router is part of a domain network that uses DNS for address resolution. You can enter the data under Network > DNS.

Name	Description	Default
Primary DNS	Set primary DNS	Blank
Secondary DNS	Set secondary DNA	Blank

DNS Relay

When DNS relay is enabled (by default, if DHCP is set up), the IP address of the router is assigned to the DHCP clients as the DNS server. All DNS requests to the router are forwarded to your ISP’s DNS servers. If DNS Relay is disabled, the Router assigns the ISP’s DNS servers to the DHCP clients. You can access these settings via Services > DNS Relay.

With the Add button up to 20 DNS pairs can be created.

Name	Description	Default
Enable DNS Relay	Click to enable DNS forwarding	Enabled (after enabling DHCP)
Static (IP Address <-> Domain Name) Pairing (maximum 20 DNS pairs)
IP Address	Set IP address <-> DNS pairs	Blank
Host	Set names of IP address<->DNS pairs	Blank
Description	Describe IP address<->DNS pairs	Blank

DDNS (Dynamic DNS)

DDNS or dynamic DNS is used if the WAN connection does not have a fixed public IP address, but services are still to be accessed externally. Since the IP address of the provider can change again and again with a normal WAN connection, a secure setup, e.g. of a VPN tunnel, is not possible. Therefore one uses providers of dynamic DNS servers, which ensure that your WAN connection always gets over the IP address. You can reach the configuration via Network > DDNS.

Name	Description	Default
Current Address	Show current IP address	Blank
Service Type	Select DDNS provider	Disabled

There are various setting options for different DDNS service providers. These are selected via the service type.

No-IP is used here as an example for the setup. For this, you need a No-IP account, which you have to create yourself. There are various providers here, some of which are free of charge, but some of which are subject to a charge. The assignment of the Dynamic DNS can be assigned to the WAN as well as to the dialup connection.

Name	Description	Default
Service Type	DynDNS - Dynamic	Disabled
URL	http://www.dyndns.com/	Set
Username	Registered username for
DDNS	Blank
Password	Registered password for DDNS	Blank
Hostname	Registered hostname for DDNS	Blank
Wildcard	Can be activated if wildcard is to be used	Disabled
MX	Entering an MX record	Blank
Backup MX	Can be activated if MX-Record should run as backup	Disabled
Force Update	Forces the update of the account	Disabled
Last Update	Shows when the IP address was last changed
Last Response	Indicates the last time communication was made with the service

DTU

DTU stands for Data Terminal Unit and is used to connect devices with serial interface (RS-232 and RS-485). You can create the configuration under Services > DTU. If DTU is activated, the console port is automatically deactivated.

Name	Description	Default
Enable	Click to activate DTU	Disabled
DTU Protocol	Set DTU protocol	Transparent
Protocol	Possible options are “TCP” and “UDP	UDP
Mode	Set DTU as client or server, depending on DTU Protocol selection possible	Client
Frame Interval	Set the frame interval in milliseconds	100 msec
Serial Buffer Frames	Default buffer frames	4
Multi-Server Policy	Selection between Parallel and Poll	Parallel
Min Reconnect Interval	Min Reconnect Interval	15 Sec
Max Reconnect Interval	Max Reconnect Interval	180 Sec
DTU ID	Default ID for the DTU	Blank
Source IP	IP address of the source computer	Blank
DTU ID Report Interval	Time interval for sending the DTU ID	0
Source IP	IP address of the source computer	Blank
DTU ID Report Interval	Time interval for sending the DTU ID	0
Multi Server
IP-Adresse	Set up IP address for receiving data	Blank
Server Port	Set up server port for receiving data	Blank

Depending on the selection of the DTU protocol, the selection fields may vary.

SMS

The TK500 can be reached from outside via SMS and reacts to various commands sent via SMS. You have the possibility to query the status of the device or to restart the device. The router is configured via Services > SMS.

Name	Description	Default
Enable	Click to enable or disable SMS control	Disabled
Status Query	Set status request SMS to display the status of the router via SMS (e.g.: show status).	Blank
Reboot	Lets the router restart (e.g. reboot)	Blank
SMS Access Control
Default Policy	Block or Accept control SMS from specific phone.	Accept
Phone Number	Enter phone numbers to send SMS to router. The format for mobile number is 491712345678 (please do not enter +49 or 0049)	Blank
Action	Accept or block the previously entered phone number	Accept
Description	Description for the created dataset	Blank

To be able to send an SMS to the router, the mobile number of the inserted card must be known. The SMS is then sent to this number.

SMS that you receive on your cell phone:

Host: (SN);

Uptime: (the operating time of the router at the time of this reboot);

State: (Online/Offline) (Radio-WAN-IP)

LAN: (Ready) (LAN-IP)

Traffic Manager

The Traffic Manager can be used to provide the data consumption of the dial-up connection interface. You can configure this service under Services > Traffic Manager.

Name	Description	Default

Alarm Threshold	Sets the amount of data in MB per month at which an alarm should be generated. If 0 is set as value, no alarm will be generated	Blank
Disconnect Threshold	If the set value is reached, the dial-up connection is interrupted	Blank

The amount of data used can be checked at any time under Traffic Statistics (see 3.8.3).

Alarm Manager

The Alarm Manager can be used to generate various alarms. You can configure this service under Services > Alarm Manager.

Name	Description	Default
Alarm Input	Select here the areas for which an alarm is to be generated	none
Alarm Output	Here you can choose whether the alarms should be issued via the console or not	selected
