System Users
Summary
The System Users page is used to add new user accounts that can access the device with different user credentials than the default ones. The newly added users can be assigned to one of two groups, either of which can be modified to limit WebUI read/write access rights for users belonging to each specific group.
This page is unrelated to SSH users. By default, there is one SSH user named "root" and it shares the same password as the default WebUI user named "admin".
This manual page provides an overview of the Users page in TRB255 devices.
If you're having trouble finding this 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 "Advanced" button, located at the top of the WebUI.
Groups
The Groups section lists available user groups of which there are three:
- root - highest level of authority. Key elements that define this group:
- has unlimited read/write access;
- additional users cannot be added to this group;
- access rights for this group cannot be modified.
- admin - second highest level of authority. Key elements that define this group:
- limited read access; by default, users belonging to this group cannot view these pages:
- System → Administration → Users Settings → System Users
- System → Administration → Profiles
- System → Maintenance → Backup
- System → Firmware
- System → Maintenance → CLI
- System → Setup Wizard
- System → Maintenance → Custom Scripts
- limited write access; by default, users belonging to this group cannot view these pages:
- System → Administration → Users Settings → System Users
- System → Maintenance → Backup
- System → Firmware
- System → Maintenance → CLI
- System → Setup Wizard
- System → Maintenance → Custom Scripts
- System → Administration → Access Control → General
- System → Administration → Profiles
- access rights can be modified.
- limited read access; by default, users belonging to this group cannot view these pages:
- user - lowest level of authority. Key elements that define this group:
- no write access;
- limited read access; by default, users belonging to this group cannot view these pages:
- System → Administration → Users Settings → System Users
- System → Firmware
- System → Maintenance → Backup
- System → Administration → Access Control
- System → Maintenance → CLI
- System → Maintenance → Custom Scripts
- System → Maintenance → Troubleshoot
- System → Package Manager
- Network
- System → Setup Wizard
- Services → Hotspot → General → Userscripts
- Services → Mobile Utilitites → Messages → Send Messages
- access rights can be modified.
Additional note: you can view and/or edit settings for each group by clicking the 'Edit' button next to them. More on information on how to edit group access settings is located in the following section of this manual page.
Group Settings (edit group)
A group's parameters can be set in its Group Settings page. To access the Groups Settings page, click the 'Edit' button next to the group's name. Below is an example of the Group Settings section:
Field | Value | Description |
---|---|---|
Write action | Allow | Deny; default: Allow | Specifies whether to deny or allow write access for users belonging the group. |
Write access | path(s) to page(s); default:
|
Controls the ability of users to change and execute the contents (e.g. Network > Lan). |
Read action | Allow | Deny; default: Deny | Specifies whether to deny or allow read access for users belonging the group. |
Read access | path(s) to page(s); default: in the picture above | Path(s) to the page(s) to which the selected "Read action" will be applied. Click the plus symbol to add more entries. |
Examples
The easiest way to master the syntax is to navigate to page that you want to generate a path for and the copy the path from the URL of that page.
For example, to specify the path to the Network → Mobile page, navigate to the page, copy the page's URL address starting from the symbol "#" and paste it into one of the access fields:
However, the VPN window contains links to many different types of VPN pages. If you want to specify only one of them, you can do it as well. For example, to to specify the path to the IPsec page, add "/ipsec" to the path string:
services/vpn/ipsec
An asterisk (*) in the path string means that the every page from that point on is included in that path. For example, to generate a path that includes pages in the Services menu tab:
services/*
Or to simply include everything in the entire WebUI (if this path is combined with Read action: Deny, users from that group will not be able to login to the WebUI):
*
Users
The Users section lists all created users and provides the possibility to change their passwords and the group they belong to (with the exception of the default user "admin" which always belongs to the root group).
By default, there is only one user called "admin":

Certificates
The Certificates page is used for convenient TLS certificate and key generation and management. Generated files can be exported and used on other machines or locally on this device with functions that use TLS/SSL, such as MQTT, OpenVPN, IPsec and others.
Certificate Generation
The Certificate Generation tab provides the possibility to generate TLS certificates required for secure authentication and communication encryption used by some of the devices services.
There are six distinct generation methods (denoted by the selected 'File Type').
- Simple - generates and signs a set of 2048 bit certificate and key files that include:
- Certificate Authority (CA)
- Server certificate & key
- Client certificate & key
- DH Parameters
- CA - generates a Certificate Authority (CA) file. A CA is a type of certificate file that certifies the ownership of a public key by the named subject of the certificate. In other words, it assures clients that they are connecting to a trusted server and vice versa.
- Server - generates a server certificate and key. A server certificate validates a server's identity to connecting clients, while a key is responsible for encryption.
- Client - generates a client certificate and key. A client certificate validates a client's identity to the server that it's connecting to, while a key is responsible for encryption.
- DH Parameters - generates a Diffie-Hellman (DH) parameters file. DH parameters are used in symmetric encryption to protect and define how OpenSSL key exchange is performed.
- Let's encrypt - generates SSL certificate.
- SCEP - generates SCEP (Simple Certificate Enrollment Protocol) certificate.
Generation Parameters
Generating each type of file requires setting some parameters. This section provides an overview for parameters used in Simple and TLS certificate generation.
Simple file parameters
Field | Value | Description |
---|---|---|
Hosts | string; default: none | Appends hostnames to certificates. |
IP addresses | IPv4 address; default: none | Appends IPv4 addresses to certificates. |
TLS parameters or simply parameters that apply to each (CA, Server, Client, DH) file type are the size and common name of the generated file(s).
Field | Value | Description |
---|---|---|
Key Size | integer; default: 2048 | Generated key size in bits. Larger keys provide more security but take longer to generate. A 2048 bit is the preferred option. |
Name (CN) | string; default: cert | Common Name (CN), aka Fully Qualified Domain Name (FQDN) is a parameter that defines the name of the certificate. It should be chosen with care as it is not only used for easier management. For example, the Common Name should typically hostname of the server. It may also be used to differentiate clients in order to apply client-specific settings. |
Subject information is not mandatory but can be used as user-friendly way to identify the ownership of certificate files by including such information as the owner's location and company name.
The Sign the certificate slider control whether the certificate will be signed automatically or manually after the generation is complete.
Field | Value | Description |
---|---|---|
Days Valid | integer; default: 3650 | Length of the signature's validity. |

Certificate Manager
The Certificate Manager page displays information on all certificate and key files stored on the device and provides the possibility export these files for use on another machine or import files generated elsewhere.
Certificate Import
The Certificate Import section provides the possibility to import certificates and files generated on another machine. To upload such a file simply click 'Browse' and locate the file on your computer, it should then start uploading automatically.
Certificates, Keys & Requests
The Certificates, Keys and Requests section display files generated on or imported to the device along with the most important information related to them.
By default, the lists are empty. A set certificates generated using 'Simple' file type would look something like this:
The 'Export' buttons are used to download the files from the device onto your local machine. The 'X' buttons located to the right of each entry are used to delete related files.
Root CA
The Root CA section is used to add a root CA certificate file to the device. There is a default file already preloaded on the device which will be overwritten by any uploaded file. The certificates must be in .pem format, maximum file size is 10 KB. These certificates are only needed if you want to use HTTPS for your services and the default file should be sufficient in most cases.
Profiles
Summary
Configuration profiles provide a way to create multiple distinct device configuration sets and apply them to the device based on current user requirements. This chapter is an overview of the Profiles page in TRB255 devices.
Configuration Profiles
This section displays user defined configuration profiles:
To create a new profile, configure the device in accordance with your needs, go to this page, enter a custom name for the profile and click the 'Add' button.
