Design / Traffic Flow Question

Will the LTM SNAT the return traffic?

 

So traffic comes from client to VIP - VIP forwards to proxy and does SNAT - proxy sends traffic to new DMZ LTM back through internal LTM - LTM routes to DMZ proxy.

 

 

So at that last point when the traffic comes back from the proxy to the LTM - will the LTM do another SNAT when it forwards to the DMZ?

 

 

From what i can see, no. Since our DMZ firewall only permits traffic from the proxy IP address. However when i do TCP dumps on the internal proxy i see return traffic going through the internal LTM.
