Blackbox pentest 2

In blackbox pentest 2 , we use proxychains and sock_proxy to access a webserver on another network. My question is can we access it using the method in blackbox pentest 1 , by portfwding to our LHOST and running nmap scan against it and access through web browser. If not then why ?

thats a great idea because i’m having a heck of a time discovering anything on the new IP i found on the first vuln computer. after nmapping with proxychains and all its not showing anything, and i recieve different results from the solutions tabs…even if followed step by step

I am having this issue too. not only with the 2nd lab also with the first.
i even get same results in for 2nd machine in both labs, but seems to be nowhere in
