Connecting iPollo and Jasminer Miners to Mining Rig Rentals Using FXMinerProxy

The iPollo V1 Mini, Jasminer X16-Q, and Jasminer X4-1U can connect to Mining Rig Rentals through FXMinerProxy. This guide explains how to install the proxy, configure its connection to MRR, and point your miners at it.

FXMinerProxy runs on a separate computer or server. Your miners connect to that computer, and the proxy connects to your MRR rig:

Miner → FXMinerProxy → Mining Rig Rentals → Your pool or the renter’s pool

Install FXMinerProxy on your computer or server—not on the miners. The project provides Linux and Windows versions. FXMinerProxy is third-party software; review its terms and any applicable developer fees before use.

1. Prepare your network and MRR rig

Use an always-on computer or virtual machine with a stable network connection. For this walkthrough, place it on the same local network as your miners and give it a fixed IP address or a DHCP reservation.

The examples use:

Replace the example IP address with your proxy computer’s actual address. Port 13344 is a local port you will create in FXMinerProxy; it is not your MRR rig’s assigned port.

This example uses Ethereum Classic. Keep the miner’s coin or algorithm setting, the proxy’s coin selection, and the MRR listing’s algorithm consistent. An Ethash setup requires the corresponding Ethash configuration instead.

Obtain your MRR connection information

Create or open your rig on Mining Rig Rentals, then open its connection information.

For this setup, use the direct/assigned rig connection:

1. Click the red rig port button in the rig’s connection information.
2. Copy the displayed server hostname and assigned port.
3. Copy the rig’s worker name and mining password.

Keep the hostname and port together. The assigned port is specific to that server; it cannot be reused with another MRR hostname. The direct connection bypasses the initial Stratum redirect.

Configure a working pool in your MRR rig’s pool settings for use while the rig is not rented. Test with a pool that supports the rig’s selected algorithm.

Your normal pool address belongs in MRR’s pool settings. FXMinerProxy’s upstream destination will be MRR—not that pool.

2. Install FXMinerProxy

Choose the instructions for your proxy computer’s operating system.

Linux: Debian or Ubuntu

Use a dedicated machine or virtual machine. The official installer runs with root privileges, changes system limits, and replaces /etc/rc.local when configuring startup on Debian and Ubuntu. Do not run it on a shared server without reviewing those changes.

Open a terminal and install the required download tools:

sudo apt-get update
sudo apt-get install -y curl wget ca-certificates

Download the official installer:

curl --fail --location \
  https://raw.githubusercontent.com/FxPool/FXMinerProxy/main/install.sh \
  --output fxminerproxy-install.sh

Review the downloaded script, then run it:

sudo bash ./fxminerproxy-install.sh

These commands use the installer published by the official FXMinerProxy project.

Select English, then select Install from the menu. When installation finishes, press Enter when prompted to start the proxy. Record the administration port, username, and password printed after startup. The installer generates these values; do not assume a fixed administration port or default login.

Windows

Download the Windows package from the official FxPool/FXMinerProxy GitHub project, under Deployment → Windows System.

Extract the entire ZIP archive to a permanent folder, then run run.exe as administrator. Use run.exe, rather than launching another executable from the package directly; it is the project’s documented launcher.

Record the PORT, USER, and PASS values printed in the console. Leave the proxy running while your miners are connected.

For an always-on setup, disable sleep on the proxy computer and arrange for the proxy to start after a reboot. Verify that startup works before making the rig available for rent.

3. Open the FXMinerProxy control panel

From a browser on your local network, open:

http://192.168.1.20:ADMIN_PORT

Replace ADMIN_PORT with the PORT value printed by FXMinerProxy. Sign in with the corresponding USER and PASS values.

The administration port and mining port serve different purposes. Your browser uses the administration port. Your miners will use the mining port created in the next section.

Keep the administration interface restricted to your management computer or trusted local network. Do not expose it to the public Internet.

4. Configure FXMinerProxy’s connection to MRR

Add MRR as a target pool

Select ETC in FXMinerProxy’s coin selector for this ETCHash example. Open Target Pool, choose Add Pool, and enter:

For a standard non-TLS MRR connection, enter the address in this form:

MRR_HOSTNAME:MRR_ASSIGNED_PORT

Replace both placeholders with the values copied from your rig. Save the target pool. FXMinerProxy’s target-pool configuration stores the destination name and address.

Do not enter your proxy computer’s local IP address here. This field tells FXMinerProxy where to connect upstream.

Create a mining port

Open Port Table and add a port. Configure it as follows:

Save the configuration and ensure the port is switched On. These settings are in FXMinerProxy’s port configuration; wording may vary slightly between versions or interface languages.

Leave Pool mode disabled for this setup so you are not deliberately replacing the miners’ login identities with a unified wallet and worker.

Use the coin-specific Port Table configuration above, not the separate Pure Forwarding feature. That feature is a different forwarding configuration and is not the setup described here.

Allow local mining connections

In the proxy computer’s firewall, allow incoming TCP connections to port 13344 from your miners’ IP addresses or local subnet. Keep the administration port restricted separately.

For this local-network setup, do not create Internet-facing router port-forwarding rules.

Your miners’ connection address is now:

stratum+tcp://192.168.1.20:13344

5. Connect the miners

Start with one miner. Once accepted work is flowing through MRR, configure the remaining devices.

Use these values in the miner’s primary pool entry:

Use the MRR rig’s worker name—not your destination-pool wallet address. Copy it exactly, including its rig identifier. Do not append an extra device suffix to the worker name. For multiple devices on one listing, use that listing’s connection credentials; MRR also supports password identifiers for distinguishing miners where the mining software passes them through.

The mining password is separate from your MRR website login password and the FXMinerProxy administration password.

iPollo V1 Mini

Open the miner’s local IP address in your browser and sign in.

Navigate to:

Configuration → Miner Configuration → Pool Configuration

Replace the Pool 1 URL, Worker, and Password with the values in the table above. Save the configuration using Save & Apply, and allow the miner to reload or restart as required. The iPollo manual documents this configuration path and these pool fields.

Repeat this process for each V1 Mini you are connecting.

Jasminer X16-Q

Open the miner’s local IP address in your browser and sign in.

Navigate to:

Settings → Miner

Enter the proxy URL and MRR credentials in Pool 1. Set Coin Select to ETC for this example, rather than an ETC+ZIL dual-mining option. Save using Update or Submit, depending on the firmware interface.

Keep unrelated frequency and performance settings unchanged during the connection setup. Allow initialization to complete before assessing its hashrate.

Jasminer X4-1U

Open the miner’s local IP address in your browser and sign in.

Open the Miner configuration page. Enter the proxy URL and MRR credentials in Pool 1, select ETC/ETCHash, and click Update.

Allow the miner to initialize. The X4 manual advises allowing approximately 30 minutes before checking its reported hashrate after startup; do not repeatedly restart it simply because hashrate is not immediately visible.

Check backup pool entries

Review Pool 2 and Pool 3 on every device. Avoid leaving old external-pool entries that could take the miner away from MRR during a rental. Where a backup connection is configured, it should preserve delivery to the appropriate MRR rig.

6. Verify the complete connection

Check the connection at each stage:

An “Alive” or “Connected” status alone is not enough. Confirm that accepted work reaches the destination pool through MRR. Use sustained delivered hashrate—not a brief local peak—to set your advertised rig speed.

Before making the rig available, test a proxy-computer reboot and a miner restart while the rig is not rented. Confirm that the proxy returns, the miner reconnects, and accepted work resumes without manual intervention.

Connecting multiple miners or separate MRR rigs

Multiple miners on one MRR listing

For one combined rig, configure each miner with the same proxy URL and the same MRR rig credentials. All devices must mine the same algorithm, and the listing should advertise their combined sustainable hashrate.

For example, several iPollo V1 Mini miners could all use:

Pool URL: stratum+tcp://192.168.1.20:13344
Worker:   The same MRR rig worker name
Password: The rig’s mining password

Separate listings for each miner or group

For separate rentals, repeat the target-pool and local-port setup for each MRR rig. A straightforward layout is:

Configure each device with its corresponding local port and that listing’s MRR worker credentials. Allow the additional local ports through your firewall.

Troubleshooting

The miner does not appear in FXMinerProxy: Recheck the proxy computer’s IP address, the local mining port, the port’s On/Off state, and the firewall rule. Make sure the miner is using the mining port—not the web administration port—and that the configured listener is TCP.

The miner appears in FXMinerProxy but the MRR rig stays offline: Check the selected target pool and the complete worker name. Recopy the assigned hostname and port from MRR, especially after changing the rig’s primary server. Assigned ports are server-specific.

The rig connects but has no accepted shares: Check the algorithm at every stage, the pool configured in MRR, and any rejected-share messages. Let miner initialization finish before judging the result. A connection without accepted work does not establish a working rental setup.

Everything stops when the proxy computer sleeps or restarts: Keep the proxy computer awake and verify automatic startup. All miners using that proxy depend on it remaining available.

When contacting MRR support, include your rig ID, miner model and firmware version, FXMinerProxy version, local-port settings, selected MRR endpoint, and relevant connection or rejected-share logs. Remove administration passwords and other private credentials from screenshots.
