My network setup is:
- First router+modem connected to ADSL cable
- Second router is connected via LAN to WAN to the first router
- My computer is connected to the second router via ethernet cable.
- there is no configuration on the first router i just connected the second router with ethernet cable to the first router.
My question is if someone has access to the network of the first router+modem can he eavesdrop on my computer's communications?
And if the answer is "yes", is there something I can do when I believe that the first router that is connected to the internet has very poor security, especially against man in the middle attacks?
The first router is from my ISP and is very cheap, without many options in the web panel. I can't replace it because my home telephone is connected to it.
the Wifi in the second router are disable i connected only via ethernet cable.
