BE-Client ULTRA Appliance Image — Ready for microSD

This page always carries the latest Boteraser ULTRA ARM image. Write it to a microSD card, put the card into ARM hardware with two network cards, and the appliance boots ready to protect the servers behind it.

Boteraser ULTRA ARM Image (latest)

Download the latest Boteraser ULTRA ARM image and write it to a microSD card — with balenaEtcher, Raspberry Pi Imager or dd. The card then goes into ARM hardware that has two network cards, such as the NanoPi R3S LTS: connect one port to your uplink (router or switch) and the other to the servers you protect, and power the board on. Nothing is installed on the protected servers themselves.

The image boots with both ports already joined in a bridge, and the appliance answers on 192.168.0.1. Open it in a web browser:

http://192.168.0.1

and sign in with the default credentials:

User name: admin
Password: boteraser


Change that password right after the first sign-in, under Account — the bridge shares one network segment with the uplink and with the servers behind it, so until you do, anything on that segment can sign in.

Then open Settings and enter your ULTRA API key (you can get it at: https://user.boteraser.com/api.php), list the networks and servers you protect under PROTECTED_NET so they are never blocked, and change the bridge address if 192.168.0.1 is already used by a router upstream.

The interface shows what is blocked and why, live traffic with its fingerprints, the threat lists, your own allow and deny rules, and the full configuration of the appliance.

✅ That’s it! The board now runs Boteraser ULTRA continuously, fingerprinting every source that crosses the bridge and blocking bots, scrapers and blacklisted IPs before they reach the servers you protect.
