Natbypass port forwarding

We have learned before ssh Port forwarding 、 Firewall port forwarding 、rinetd Port forwarding 、nc Port forwarding 、socat Port forwarding 、portmap Port forwarding 、portfwd Port forwarding , Today we are going to study NATBypass Port forwarding ,NATBypass Is a go language-written LCX, abbreviation nb, In the experiments win7 With nb.exe and kali With nb All are GitHub Download the , among kali Upper nb I compiled it myself , Since it is LCX Then the usage is the same , Let's go straight to it ～

Experimental environment ：

• macos：192.168.199.206
• kali：192.168.199.247
• win7：192.168.199.185

First step ： Borrow the springboard kali, Log in to the intranet host remote desktop

Monitor on the gangplank 2 Ports ,6666 Port and intranet win7 signal communication ,7777 Ports and hackers macos signal communication

The second step ： In the intranet host win7 Admiral 3389 Port and springboard 6666 Ports are connected

The third step ： In hacking macos Visit the springboard 7777 port , From the springboard kali Of 6666 port , Flow into Intranet win7 Of 3389 port

Again , It can also be as simple as one step , Just on the springboard kali On the configuration , It doesn't need to be on the intranet win7 On the configuration

then macos Connect kali Of 6666 port , It can also realize remote login win7

Network security has a long way to go , Wash and sleep ～
