Hi David,
Thank you for the response.
If you could point me in the right direction for configuration. That'd be
great.
Requirements:
* Operate a server on the Internet on [203.16.25.202] (example IP)
* The interface on the server host must be set to the same
[203.16.25.202] IP
Environment:
* Server host on PSN of Gnatbox
* Traffic to/from server host must NOT be NATed
* [203.16.25.202] is part of a block of nine assigned static IPs which
itself is part of the [203.16.25.0] class C network
* EXT interface on GB set to [203.16.25.203], Remaining eight IPs set
up as aliases
* The block of nine IPs, arrives routed on the [203.16.25.0] class C
network
* Network = [203.16.25.0]
* Bdcst = [203.16.25.255]
* Default Route = [203.16.25.1]
Regards,
Jon Schlegel
