NettForge for IT Network toolbox

The network toolbox for ISP and MSP technicians

Is it up, is the loss real, does the line match the plan, what changed on the router, and how healthy is the dish. All from one app, saved to the client's history.

Most network problems start with the same questions. Is it up? Where is it slow? Is the line giving the client what they pay for? Is that dish aligned? The NettForge Windows app puts the answers in one toolbox, runs them against the right client, and saves every result to that client's history.

Is it up? Type the address any way you like

Paste https://10.20.0.5:8443/manage, 10.20.0.5:8443 or just 10.20.0.5. The Quick test works out what you meant, then tries ping, the port you typed and the usual management ports, and gives one plain sentence: Up: answers ping and Secure web 8443. A device that blocks ping but answers on its port is correctly shown as up. Find more names what answers on about 40 common ports, and Find the right web address lists the page that really loads. Tests run for as long as you like, with a Windows notification the moment something drops. Three tests on one device give one alert.

Path test: is the loss real?

A traceroute shows the path once. The path test keeps going, pinging every stop again and again, and tells you the truth about loss: a middle router that does not answer ping is normal and is not a fault, but loss that carries on to the end of the path is real, and the first stop where it begins is named. A delay that starts at one stop and stays is named too.

Speed test against the plan

Measure the line you are plugged into: reply time, download and upload. Enter the speed the client pays for and the test says whether they are getting it, what the line is good for, and how it compares with the last result saved for that client.

Config backup: what changed?

Save a MikroTik's configuration over SSH, with passwords left out, into your encrypted vault. Run it again later and NettForge shows exactly what changed, grouped by menu, with changes to the firewall, users, services, scripts and VPNs flagged. Back up every router of a client in one go.

Read a client's MikroTik, Ubiquiti airOS radio or any SNMP device and get signal, noise, signal over noise, link quality, and fibre light levels, each with a plain word (good, low, critical) and what to do about it. A sector lists its customers weakest first, and the trend against the last reading shows when a dish has drifted.

And the everyday ones

ToolWhat it answers
Port check and port finderWhich services answer on a device.
Web checkStatus, speed, redirects and certificate of a page, and the right address if yours does not load.
TracerouteThe path hop by hop, with the exact slow stop.
Lag under loadDoes the line stutter when it is busy (bufferbloat)?
Largest packet that fits (MTU)The right MTU for a link with PPPoE, a tunnel or a VPN.
DNS lookup and certificate checkDo servers agree, and how many days are left on a certificate?
Who owns this, reverse lookupWhose address is this?
MikroTik toolsInterfaces, wireless clients, DHCP leases, routes and ping from the router.
Wake on LAN, subnet calculator, device maker lookupThe small things you always need.
Is it them or us?Is a service like DStv or Netflix down, or is it this network?

Every result can be copied, printed or saved to the client's history, which also makes a good record when a client asks what happened. See the whole picture in password management for ISPs and MSPs, and how logins work in WinBox and SSH login automation. Which plan includes which tools is on the pricing page.

Questions people ask

Yes. A web browser is not allowed to open raw network connections, so the tests run in the NettForge Windows app. Your clients, devices and saved results are shared with the web vault.

Yes. A client can have its own WireGuard tunnel that runs inside the app, and the tests (apart from ones that cannot travel through a tunnel, such as a trace) use it.

No. The MikroTik, config backup, and link health tools only read. Nothing is changed on a router or radio.
