Duplicated WAN Creation

elanderson · December 3, 2025, 8:41pm

Hi! Hope it finds you well.

It’s been basically 2 years since we first implemented GenieACS, and in the last month we opened around 70 Service Orders for customers claiming not having internet.

The thing is, once we access their router, there are 2 PPPoE Wan created, check it out:

At first i thought on some missconfigured settings on provision, but after spending all day trying to reproduce this on production i couldn’t find any problem on the script itself.

Does anyone here could notice if our configuring script has any interaction that could lead to this kinda of error? Creating another PPPoE i say.

The only thing i thought of was if the technician created a 3rd wan manually, then, the filter on checkWAN() wouldn’t work i guess, but even if it happens, the following line should keep only 1 instance of PPP Wan, right?

declare(`InternetGatewayDevice.WANDevice.1.WANConnectionDevice.1.WANPPPConnection.*`, null, { path: 1 });

Check the full script:

// Auditoria das ONTs\\

const now = Date.now();
const provisionado = declare("Tags.Provisionado", { value: 1 })?.value?.[0];
const bootstrap = args[0];
log(`provisionado: ${provisionado} || bootstrap: ${bootstrap}`);

if (provisionado && !bootstrap) {
  bindLANToWAN();
  log("CPE está (supostamente) configurada, retornando...");
  return;
}

Your syntax is incorrect.

Here is a corrected version of one of your functions.

function declareWanPppConnection(WANConnectionDevicePATH, username, password) {
    log('>> Atualizando valores WANPPP Base...');
    
    const basePath = `InternetGatewayDevice.WANDevice.1.WANConnectionDevice.${WANConnectionDevicePATH}.WANPPPConnection`;
    const params = {
        Name: '2_INTERNET_R_VID_10', // Or what ever you want to call it
        Enable: true,
        MaxMTUSize: 1492,
        MaxMRUSize: 1492,
        CurrentMRUSize: 1492,
        DNSEnabled: true,
        NATEnabled: true,
        Username: username,
        Password: password,
    };
    
    // Delete all existing PPP entries
    declare(basePath + '.[]', null, {path: 0});

    // Add back in the only one we allow
    const path = basePath + '.[' + Object.keys(params).map(key => key + ':' + params[key]).join(',') + ']';
    declare(path, {path: 1}, {path: 1});
}

Thank you so much once again, Dan!

We’ll implement it here and see if it’s gonna fix our problem (probably will). Are there any other recommendations?

Just tried applying it, but this kept happening. Instead of deleting both wanPPP it kept deleting and adding until RPC too may requests crashed the running of the script and not finishing everything, like binding internet to LAN and WLAN, remote management, etc.

Why is it happening?

Re-read the output. Then enable debug and try again and review the output in the debug yaml file.
