  • 1.  Multiple MIP and NAT

    Posted 02-07-2014 08:12

    Hi everyone!

     

    On a SSG320 there are 3 MIPs pointing to the same private IP address.

    How can I know which one is used by default when the device has outbound connections?

     

    Thanks.

    I would initiate an outbound ping to a fresh unique destination then look for the traffic in the logs.

     

    One way to control this would be to leave only the one MIP in place and create two policy based destination nat for the other two inbound connections.  This would insure a consistent usage of the address you prefer.

    Hi Steve, thanks for your suggestion.

    However, I found this KB which explains exactly my situation:

    The last MIP address added is the one visible from external. If you want to change it, you have to change the order.
