The next question.
There is a router DFL-800. From outside, it comes to a lace from the provider. Within the enterprise conventional network \\24.
Because we rent not one ip, and the subnet is available to us already 3 external ip addresses. At the moment, was configured one IP and all the necessary accesses and operations to internal servers from the external network, we have been through the SAT/NAT.
At the moment, need to use another IP address (external). It has to be bound to a physical server, which is, of course behind a router. Opened such a thing as a DMZ. But did not catch the logic configuration and use. Ie the following questions:
1. How to hang 2 external ip address on a physical Ethernet interface.
2. As a fully mirrored to forward the requests on all ports from the external IP to the internal.
