What happens when you swap a modem and router out with a different modem and router?
Can you achieve full isolation by alternating between which network is plugged into the Internet line?
I am looking for full isolation of a honeypot computer while protecting a secure personal computer. I have a single DSL internet line.
It would look like this:
--Internet-- modem A - router A - secure computer modem B - router B - honeypot computer
If I change the cable back and forth between network A and network B, is there ANY way of the honeypot and/or an attacker influencing network A's modem, router, or secure computer?
By swapping modem and router:
Does your internet line IP address change?
Does it appear to the Internet as though you have an entirely different DSL Internet line running to your house?
Could an attacker, that has entered the honeypot on network B still see the network A after I unplug network B and connect network A back to the Internet?
Are there ports that an attacker could use on network A if said attacker has compromised the honeypot network?
