Router traffic

Tarasque · January 3, 2021

Hi,

For month now due to covid i'm working from home and my office computer is with me, it has VPN and i know it is monitored but i think that they might be monitoring and my personal computer and my router traffic.

How can i find out if i'm right ? sometimes there are some really strange slowdowns on the speed that never happened before.

I connect my office pc with my office phone via USB tethering and phone is connected to the wife.

I'm trying never to connect them at the same time, when I finish work i just disconnect the pc but if they have access to my router could they monitor the traffic even when the office pc is disconnected?

With a normal router and without knowledge of packet captures, its not that easy to find out, but as someone that works in it, and works from home systems, IT probably isn't doing anything weird.

If your worried, most routers have a guest mode that keeps devices from talking to other devices on your home network. Put the work computers on the guest network.

My router is pretty basic tp-link for 15$ yes, any idea how can i check if the firmware is hacked. Is PRTG good tool for packet captures ?

Let me get this right, you have a fairly boring home network and you have been provided an office computer which dials into the actual office over a VPN and you do your work that way?

This sounds fairly straight forward and there's not a lot they could potentially do to monitor the rest of your network, if anything, they should be the ones concerned about putting company equipment on an unmonitored staff members personal home network.

If the VPN is disconnected on the work provided machine then they will have no access to anything on your network real-time.

All that you could really do if you're actually paranoid and willing to spend the money is buy a decent router with some firewall customisation capabilities, put the work PC in a different security zone and make rules such that it can only talk out the WAN and not to other LAN on the router.
