RISE as TIaas-Provider

WireGuard Configuration

Step 1 - Import Configuration Step 1 Import Configuration
First, a new WireGuard connection is added under VPN WireGuard  button Add WireGuard connection. In the first step, the configuration provided by RISE is selected to simplify further setup.			Add WireGuard Connection UTMuser@firewall.name.fqdnVPNWireGuard Add RISE WireGuard connection Step 1
Step 2 - Interface Step 2 Interface
Caption	Value	Description	Add RISE WireGuard connection Step 2
Name:	RISE TIaaS	Name of the WireGuard connection
Release server networks globally:	»192.168.175.0/24	Enable the server network in which the card terminal is located
All other values should be set correctly by loading the configuration.
Step 3 - Peer Step 3 Peer
Name:	RISE TIaaS-Peer	Name of the peer of the connection	Add RISE WireGuard connection Step 3
All other values should be set correctly by loading the configuration.
Step 4 - Advanced settings Step 4 Advanced settings
All buttons are activated:			Add RISE WireGuard connection Step 4

Configure TI-Proxy

RISE provides a Connection.conf file, which contains the IP address of the connector.
Example Connection.conf:

tiaas:
  wireguard:
    ip: 172.31.34.1
  client:
    konnektor:
      url: 10.180.96.90
# This is a template to be filled by the customer. Please consult the manual how to perform the configuration
#card-terminal:

The IP address of the connector is the value under tiaas → client → konnektor → url, i.e. here 10.180.96.90.

This IP address is then used to configure the TI proxy.

Best Practice

Note

'

1. Connect the card terminal: Via Assign a fixed lease to network topology
2. Start the Wireguard Wizard and store the configuration from the provider on the UTM. Select all options in the last step of the wizard
3. network_object_for_wireguard_interface]]: Name: wg0-interface (in this example), → Type: dynamic interface, Destination: wg0 (in this example), Zone: firewall-wireguard-wg0 (in this example)
4. Create three services:
   1. Name: TI-Proxy-60000, Protocol: udp, Destination port: 60000
   2. Name: TI-Proxy-4742, protocol: udp, destination port: 4742
   3. Name: TI-Proxy-60000-TCP, protocol: tcp, destination port: 60000
5. In Package filter, open the automatically created rule with the source internal-networks and the destination wg0-networks and add a HIDENAT to the wg0-interface
6. In the packet filter, delete the rule that was also created automatically in the internal network.
   Instead, create the following three rules:
   1. source: internal-interface, destination: wg0-networks, service: TI-Proxy-4742, type: HIDENAT, network object: wg0-Interface
   2. source: wg0-networks, destination: wg1-interface, service: TI-Proxy-60000
   3. Source: wg0-networks, destination: wg1-interface, service: TI-Proxy-60000-TCP

	#	Source	Destination	Service	NAT	Logging	Action	Active	Buttons
		internal-interface	wg0-networks	TI-Proxy-4742 Protocol: udp Destination port: 4742	HN with wg0-interface	3/Min	Accept	On
		wg0-networks	wg0-interface	TI-Proxy-60000 Protocol: udp Destination port: 60000		3/Min	Accept	On
		wg0-networks	wg0-interface	TI-Proxy-60000-TCP Protocol: tcp Destination port: 60000		3/Min	Accept	On
		internal-networks	wg0-networks	any	HN with wg0-interface	3/Min	Accept	On

7. Enter data in the proxy
1. Enter the virtual connector IP - in the example 10.180.96.90
2. Enter the IP of the local wireguard interface (in this example 172.31.34.1)
3. Enter the IP of the internal interface to which the card terminals are connected (here in the example 192.168.200.1)
8. Create terminal on the connector (connector access in the example https://10.180.96.90:8443)
1. The IP address is the wireguard address of the UTM: in the example 172.31.34.1
2. Note
3. The default port is 60000
4. The Mac address is not required
9. On the terminal, the trusted room may have to be set to RU in the admin menu under TSL list
10. On the terminal, all trust blocks may have to be deleted in the Admin menu under Pairing
11. Click on Pair in the connector
12. Confirm on the terminal pair
