Hi,

You are right, there is a chance to allocate same outside address and port pair 
for different users. I will fix it (assign a block of port numbers to each 
worker).

Hi all,
        I read the SNAT plugin code and found that 2 or more worker threads may 
call  the function "snat_alloc_outside_address_and_port" to allocate outside 
address and port at the same time. Because the address and port are allocated  
from global varible snat_main.addresses , there is a chance to allocate the 
same outside address and port for different users. It would be not good for 
SNAT.
      I'm not sure I understand the code excatly. Please help me to check out 
it. Thanks!!

Regards
chu.penghong
