The information in this page is updated in accordance with 00.07.4 firmware version .

Introduction

Configuration overview and prerequisites

Before we begin, let's take a look at the configuration that we are attempting to achieve and the prerequisites that make it possible.

Prerequisites:

Two RUT/RUTX series routers with RUTOS firmware;
An end device (PC, Laptop) for configuration;

If you're having trouble finding any page or some of the parameters described here on your device's WebUI, you should turn on "Advanced WebUI" mode. You can do that by clicking the "Basic" button under "Mode," which is located at the top-right corner of the WebUI.

Topology

RUT1 - RUTX11 as a hub. It will be our "default gateway" for spoke device. RUTX11 has a LAN subnet of 192.168.11.0/24 configured on it, which should be reachable by the spoke.

RUT2 - RUT955 as a spoke. It will be connecting to a hub for basic internet access. RUT955 has a lan subnet of 192.168.9.0/24 configured on it, which should be reachable by the hub.

RUT1 (Hub) configuration

Start by configuring HUB (RUT1) device. Login to the WebUI, navigate to Services → VPN → IPsec and add a new IPsec instance. Configure everything as follows.

Note: Not specified fields can be left as-is or changed according to your needs.

Instance configuration


Enable instance; Authentication method - Pre-shared key; Pre-shared key - your desired password;

Connection configuration


Mode - Start; Type - Tunnel; Local subnet - 0.0.0.0/.0; Key exchange - IKEv2;


Enable Local firewall; Remote source IP - 10.20.30.0/24; Remote DNS 9.9.9.9;

Proposal configuration


Encryption - AES256; Authentication - SHA512; DH group - ECP521;


Encryption - AES128; Authentication - SHA256; DH group - ECP521;

RUT2 (Spoke) configuration

Login to the RUT2 WebUI, navigate to Services → VPN → IPsec and add a new IPsec instance. Configure everything as follows.

Instance configuration


Enable instance; Remote endpoint - RUT1 public IP; Authentication method - Pre-shared key; Pre-shared key - the same password you have set on RUT1 when configuring HUB instance;

Connection configuration


Mode - Start; Type - Tunnel; Enable default route; Key exchange - IKEv2;

Proposalconfiguration


Encryption - AES256; Authentication - SHA512; DH group - ECP521;


Encryption - AES128; Authentication - SHA256; DH group - ECP521;

Testing configuration

After we establish the tunnel, we may observe the following information:

RUT1 (HUB) side

Using the

ipsec statusall

command we can see that the tunnel has been established.
