Example:
CONSENT_ACCEPTED=”yes”
API_KEY=”<YOUR API KEY>”
LOG_PATH=”/var/log/nginx/access.log”
Save and exit.
Install the systemd service:
sudo cp /opt/boteraser/be-client.service /etc/systemd/system/

Boteraser ULTRA Automatic Install Script (latest)
The Boteraser ULTRA install script installs the client as an inline bridge appliance that protects every server behind it, without installing anything on those servers. It runs on a dedicated box — a spare computer you already have will do — but that machine must have two network cards: one facing the uplink (router or switch), the other facing the servers you protect. The script joins them into a bridge, enables bridge filtering and starts the be-client-ultra service, so all traffic passes through Boteraser ULTRA and unwanted traffic is dropped before it reaches your services. The ULTRA package is built for ARM64 hardware, so the installer stops on other architectures.

Boteraser ULTRA Manual Install
This is a quick manual on how to install and configure the Boteraser ULTRA client, the inline appliance that protects every server behind it. ULTRA runs on ARM64 (aarch64) hardware — boards such as the NanoPi R3S LTS, or any spare machine with an ARM64 CPU — and the machine must have two network cards joined in a bridge: one facing the uplink, the other facing the servers you protect.

Create the bridge first — the daemon refuses to start unless BRIDGE is a bridge with at least two ports:
ip link add name br0 type bridge
ip link set eth0 master br0
ip link set eth1 master br0
ip link set eth0 up
ip link set eth1 up
ip link set br0 up
eth0 faces the uplink, eth1 faces the protected servers. Make the bridge permanent in your network configuration (netplan, /etc/network/interfaces, NetworkManager) so it survives a reboot, and verify both ports are members:
ls /sys/class/net/br0/brif
Download be-client-ultra-latest.tar.gz to your preferred location (recommended: /opt):
cd /opt
wget https://github.com/sofset-dev/boteraser/raw/refs/heads/main/be-client-ultra/be-client-ultra-latest.tar.gz
Extract the archive and enter the directory:
tar -xzvf be-client-ultra-latest.tar.gz
cd boteraser-ultra
This creates /opt/boteraser-ultra containing be-client-ultra, be-ultra.conf, be-client-ultra.service, image-prep.sh and README.md. Make the binary executable:
chmod +x be-client-ultra
Edit the configuration file. Open be-ultra.conf with a text editor:
nano be-ultra.conf
or
vi be-ultra.conf
In be-ultra.conf, set at minimum:
CONSENT_ACCEPTED=”yes” – required; the software will not start until this is set to “yes”
Your API KEY – you can get it at: https://user.boteraser.com/api.php
BRIDGE – the bridge that joins the two monitored interfaces (e.g. br0)
PROTECTED_NET – the networks and servers behind the bridge, comma separated; they are never blocked and never fingerprinted
BR_MODE / BR_IP – the address the machine keeps on the bridge (“static”, “dhcp” or “none”). The default 192.168.0.1 is also the usual address of an ISP router, so change it when one sits upstream
WEB_ALLOW_FROM – the networks allowed into the built-in web interface (strongly recommended). Example:
CONSENT_ACCEPTED=”yes”
API_KEY_ULTRA=”<YOUR API KEY>”
BRIDGE=”br0″
PROTECTED_NET=”203.0.113.0/24, 198.51.100.10″
BR_MODE=”static”
BR_IP=”192.168.0.1″
BR_NETMASK=”255.255.255.0″
WEB_ALLOW_FROM=”192.168.0.0/24″
For email reports also set SMTP_HOST, SMTP_USER, SMTP_PASS and NOTIFY_EMAIL. Every option is documented in the comments inside be-ultra.conf.
Save and exit

Enable and start the service (it will also start automatically on boot):
systemctl enable –now be-client-ultra
Set the password for the built-in web interface before the machine goes inline — it ships as admin / boteraser, and the bridge shares one network segment with the uplink and with the servers behind it:
/opt/boteraser-ultra/be-client-ultra –set-password
systemctl restart be-client-ultra
The interface then answers on the bridge address (WEB_PORT, 80 by default) and shows what is blocked and why, live traffic with its fingerprints, the threat lists, your local allow/deny rules and every setting in be-ultra.conf.
Check the service status and view logs:
systemctl status be-client-ultra
journalctl -u be-client-ultra -f
The startup log prints the bridge and its ports, the address it assigned, the br_netfilter sysctls it set and the protected networks it loaded — fix anything it warns about before relying on the machine for protection.
✅ That’s it! BE-Client ULTRA now runs continuously as a background daemon on the bridge, fingerprinting every source that crosses it and dropping bots, scrapers and blacklisted IPs before they reach the servers you protect.

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.
