Netflow gathering with NAT

tchernov

When gather incoming netflow traffic with NAT, the local outside address (before NAT) as the destination is represented there normaly. But this info is quite unuseful for the accounting. Does somebody know, how to determin the local inside address (after NAT) for such a flow record?

PS: What is the "IP address of the next hop router" field in the flow record?

Not applicable

The flow capture and collection is configured already and works properly. The problem is that the supplied info doesn't match our requirements - I can't assign the record about incomming traffic to certain intranet interface because the dst-ip is from the pool of outside addresses, mapped dynamicaly.
