Hi Team, 

Please help in below scenario:- 

I have 3 machines :- machine A ( ip - 10.5.5.7, Client ), machine B(10.5.5.52, 
server ) and machine C [ callto:(192.168.13.212 | (192.168.13.212 ] ). 

Ipsec sec tunnel established between machine A and machine B. when i ping from 
A to B , ipsec whack --trafficstatus in and out byte get increase. 

Now machine C is connected with machine B through usb to ethernet converter and 
there is a route at machine A so that i can ping machine C through machine A, 
But when i ping machine C from machine A , ping get started but ipsec whack 
--trafficstatus is not increasing means outgoing packets are going through 
tunnel. 
and when i ping C to A , ipsec whack --trafficstatus showing in out bytes 
correclty. 

means when i ping A to C packets not going through tunnel but when i ping C to 
A packets going through tunnel. 

route set at machine A = route add -net 192.168.13.0/24 gw 10.5.5.52 
route set at machine C = route add -net 10.5.5.0/24 gw 192.168.13.50 

Note - 192.168.13.50 is the ip of usb to ethernet interface which connect 
machine B(server) to C. 


Expected result - I want when i ping machine C through machine A , ipsec 
traffic should get increase. 

Note - Ipsec tunnel is only between A and B , where A is client and B is 
server.
