Need help locating device by Mac address

mgalib

I have a temperature monitor connected to my network. (a requirement since we store vaccines.) In order for it to connect to the server, it needs certain ports (18888, 90, 98) opened up.

To do port forwarding on my  Comcast modem/router ( Cisco DPC 3941B), I need the local IP address for this device.  The problem is that this particular router (and according to Comcast ALL their routers) have a firmware problem that does not let me see list of connected devices. 

So what I am trying to do is find the local IP by Mac address on Fing. Unfortunately, Fing is not showing Mac addresses for most of the 'generic' devices on the network. 

So my question is (1) Can I find Mac address for ALL devices on my network using Fing? and (2) If I can't do this with Fing, is there another tool that I can use? 

Thanks in advance for your help :-)

There's your issue, then. Ever since (I think) iOS 11, Apple decided it was far better for us users to not be able to see MAC addresses on the local Network (yeah, don't ask).
In order to solve this conundrum you've a couple of choices today:
1 - Buy a FingBox ($99.00 - very highly recommended)
2 - Find an Android phone and use the App on there.

Sometime in the near future Fing will be producing a desktop version of the app, however that's not available today.

If you feel this has answered your question (not necessarily given you the MAC addresses you need) the please do mark the answer as such so other users will see it.

Welcome to the community @mgalib
Two questions for you:

1. Are you using the Fing App or do you have a FingBox as well?
2. If you're using just the Fing App, are you on iOS or Android?

@VioletChepil : Mind moving this to the Fing App category, please? Thanks!

1. I am using the Fing app. ( do NOT have Fingbox)
2. iOS Fing App

Hi @mgalib! are you using just the FingApp on an iPhone?
There is a known limitation for the iOS devices (imposed by apple) on they, MAC address is not listed.
You could use an android device to properly view the MAC addresses. (Or get a FingBox in your network xD)

Hehehe @Pooh the quickest answer of the west! xD

To go a bit further with the Comcast device, there shouldn't be any reason that you are unable to scan and retrieve information on that network.  However, I will further that to suggest that (since this is a medical field) you look into a dedicated firewall that you can manage and use the Comcast device only as a modem.  I'm sure HIPPA would certainly appreciate that, too.  Then you should be able to scan the network and obtain all connected devices from that.

(I used to work for a large blood center, we had to have all information secured and be HIPPA compliant)

Yes, the android app worked perfectly. And the problem is solved. Thanks a lot! 
@kltaylor I will look into your advice and try to implement it.
