Prefaces

Usually, the installation wizard appears during the initial setup of the UTM.
This checks whether a configuration already exists that is marked as the start configuration.

(Status )
If this is not the case, the wizard opens automatically.

It is not advisable to start the installation wizard later, as other settings made in the meantime may be overwritten.

Installation wizard

Step 1 - General

Caption	Value	Description	Step 1
Firewall Name:	firewall.ttt-point.local	This is about how the UTM responds to requests. For example, if the mail relay is to be used, it may be useful to enter the Fully Qualified Domain Name (FQDN) of the mail exchange (MX) here so that other mail servers can match it via the reverse resolution of the PTR Resource Record (PTR). This setting is not about the name under which the UTM is listed in an active directory domain. This setting is made in the Authentication → AD/LDAP Authentication → tab Settings Appliance Account entry.
Global contact person:	Alina Admin	In this field, the name of the administrator or the organization is entered, which is later specified in the UTM error messages for questions.
Global email address:	admin@ttt-point.de	Important system messages are sent to this email address.
Language of reports:	German English	Language in which the reports and system messages are sent

Step 2 - Privacy
Anonymize all applications	Yes	When activated (default), the appliance's applications are anonymized in accordance with the GDPR. Under → Authentication →Privacy anonymization can also be activated individually for each application. Should be disabled for debugging only.	Step 2
			Step 2
Step 3 - Internal
Internal firewall IP address:	192.168.175.1/24	The IP address of the internal interface (A1) as well as the subnet mask (as CIDR-notation) for the internal network.	Step 3 - with WLAN module
Dynamically assign Client IP Addresses via DHCP:	No	When enabled Yes, the UTM works as a DHCP server: All clients in the internal network receive an IP address via DHCP. This sets the UTM as the default gateway and DNS server for the clients.
Generate WLAN Bridge: Only if a WLAN module is present	No	Creates a bridge so that this network and the WLAN are on the same network.
Router advertisement: Only if no WLAN module is present	No	If the UTM has received an IPv6 prefix, it can advertise the subnet via router advertisement in the network segment behind the interface. (See article IPv6 Prefix Delegation)

Step 4 - Internet This is where the Internet connection is configured on the external interface (A0). The following variations are available:
Connection type DSL-PPPoE Connection type: ‌ DSL-PPPoE
With this type, an ADSL or SDSL modem is connected to the external interface (A0). The connection is initiated by the UTM. It must be a DSL modem. A router can be used under this connection type only if it can be set to a modem mode.
Username:	(Shares ISP)	The login information is provided by the ISP (Internet Service Provider)
Password:	(Shares ISP)

Connection type VDSL Connection type: ‌ VDSL
A VDSL modem is connected to the external interface (A0). The connection is initiated by the UTM. A router can only be used with this connection type if it can be set to modem mode and it can be guaranteed that the UTM will initiate the connection.
Username:	(Shares ISP)	The login information is provided by the ISP (Internet Service Provider)
Password:	(Shares ISP)
VLAN ID:	7	Will be supplied by the respective provider. The Deutsche Telekom usually uses, for example, the 7 as the VLAN ID.

Connection type Ethernet with static IP Connection type:‌ Ethernet with static IP
With this connection type, a router is connected to the external interface (A0), which itself initiates the connection to the Internet. The login information of the provider is stored in the preceding router and not on the UTM. This connection type cannot be used with a modem or router in modem mode.
External IP address:	192.168.178.101/24	The IP address of the external interface (A0) and the IP address range for the external network (subnet mask in CIDR notation). The default is an already existing IP address, if applicable.
Default gateway:	192.168.178.1/---	IP address of the default gateway for the UTM so that it knows which is the closest router for all networks that are not on an internal interface: As a rule: the Internet.

Connection type Cable modem with DHCP Connection type: ‌ Cable modem with DHCP e.g.: DSL connection via telephone line with Fritzbox or Speedport router. Originally mostly devices that cable providers provided to their customers.
Also with this connection type, a router is connected to the external interface (A0), which itself initiates the connection to the Internet. The login information of the provider is stored in the preceding router and not on the UTM. This connection type cannot be used with a modem or router in modem mode.

Connection type LTE / others Connection type: ‌ LTE / others LTE connections or other connections are configured after the installation wizard is completed

Step 5 - DMZ Configuration of a second internal network, often referred as Demilitarized Zone: Usually a network that is separate from the internal network. In the UTM, all networks are separated from each other by default.
DMZ IP address:	192.168.176.1/24	The IP address of the interface A2 and the subnet mask (as CIDR notation) for the DMZ network.	Step 5 with WLAN
Assign the IP addresses to the clients in this network via DHCP:	No	When enabled Yes, the UTM works as a DHCP server: All clients in the DMZ network receive an IP address via DHCP. This sets the UTM as the default gateway and DNS server for the clients.
Autogenerated rules:	No	Port filtering rules can be automatically created for this network, allowing traffic to the Internet on the interface to the external interface (A0). Likewise, rules are created that also allow traffic from the internal network into the DMZ network. These rules release all from this network to the Internet and other internal networks. These any rules are intended for testing purposes and should be disabled and replaced with well-defined rules in production mode.
Generate WLAN Bridge: Only if a WLAN module is present	No	Creates a bridge so that this network and the WLAN are on the same network.
Router advertisement:	No	If the UTM has received an IPv6 prefix, it can advertise the subnet via router advertisement in the network segment behind the interface. (See article IPv6 Prefix Delegation)

Step 6 - WLAN In the delivery configuration, a WLAN module is installed in the UTM. f the module has been removed, this step is skipped. For long-term use of WLAN (>30 days) a license is required
WLAN IP address: Not in bridge mode	192.168.177.1/24	The IP address of the WLAN interface (wlan0) and the subnet mask (as CIDR notation) for the WLAN network. In bridge mode, the setting from the internal network in which bridge mode was activated is used here.	Step 6: WLAN dialog without bridge configuration Step 6: WLAN dialog when using a bridge
Country code:	DE	The country code is used to determine which frequencies and which signal strengths may be used. The frequencies used and the transmission power can be found in a Wikipedia article.
SSID:	TTT-POINT	The Service Set Identifier (SSID) is the name under which the WLAN network is presented to the clients. This must be entered in any case.
SSID Broadcast:	On	This option can be used to define whether the WLAN network can be seen by every client or whether the transmission of the SSID should be suppressed. (Off)
Security Mode	WPA	Is considered unsafe and only exists for backwards compatibility. (TKIP is used as encryption method)
	WPA2	Standard with enhanced security AES128 is used as encryption method: https://en.wikipedia.org/wiki/WPA2
	WPA3 v12	Standard with highest available level of security AES256 and SAE are used as encryption methodes: https://en.wikipedia.org/wiki/WPA3
Assign the IP addresses to the clients in this network via DHCP: Not in bridge mode	Off	When enabled Yes, the UTM works as a DHCP server: All clients in the WLAN network receive an IP address via DHCP. This sets the UTM as the default gateway and DNS server for the clients. In bridge mode, the setting from the internal network in which bridge mode was activated is used here.
Pre-Shared key:	Don'tcopythis:Ei)#W~X$…	The base station and mobile device must have the same PSK (≙password). The security of the encryption depends directly on the length and complexity of the PSK! Short or easily guessed PSKs compromise network security.
Pre-Shared key:		Automatically generates a very strong PSK
Generate rules for Internet access: Not in bridge mode	Off	Port filtering rules can be automatically created for this network, allowing traffic to the Internet on the interface to the external interface (A0). Likewise, rules are created that also allow data traffic from the internal network into the WLAN network. These rules release all from this network to the Internet and other internal networks. These any rules are intended for testing purposes and should be disabled and replaced with well-defined rules in production mode. In bridge mode, the setting from the internal network in which bridge mode was activated is used here.

Step 7 - Administrator
User	admin	The username admin cannot be changed at this point
Password:	•••••••	The admin password insecure is already insecure because it appears in all documentation for our UTM and must therefore be replaced as soon as possible with a very strong admin password. The new password must comply with the password guidelines. Passwords must meet the following criteria: at least 8 characters length at least 3 of the following categories: Upper case Lower case Special characters Digits
Confirm password:	•••••••
Done	The wizard is being completed A new configuration is created with the name configuration-wizard-date-time This configuration is set as the start configuration This configuration is set as the active configuration

Reboot → Configuration →Restart
Do you want to reboot the system now?	Yes	In order for the configuration changes to be applied, the respective services must be restarted in the correct order. This is achieved by a reboot of the device.
If your own IP address was changed to reach the admin interface of the UTM and the default was changed in Step 3 - Internal, the internal interface of the UTM is now located in this network. For further configuration, the IP address of your own computer must then be changed again. See the [1]
