When we perform penetration testing, we can sometimes find computers which are dual-homed (having 2 network interfaces), exactly like me: I have one IP in 192.168… in my home network and a 10.0… IP on HTB.
Question: how could a penetration tester gain access to both networks, what should be done for that?
Of course the target computer has a strong anti virus, is full patched… So installing a program is unlikely to happen.
Lets say I do internal penetration testing, and I have a 192.168 IP, ok I can ping the target computer. But I would like from my computer, to be able to scan the 10.0 network, the target computer also has access to.
I know how to port forward, but in this case it would rather be “interface forward” (eth0, tun0…).
How can this be done?
Disclaimer: I will use this only on targets that give their consent (official penetration testing engagements, not for illegal activities)
