Re: [PLUG] Server behind FlowPoint 2200


| My Linux box is plugged into a FlowPoint 2200 router.  The router has
| external addresses 11.22.33.1 through 11.22.33.32 (obviously fake IPs,
| guys).  The linux box has ifconfig set to grab 11.22.33.10 and
| 11.22.33.11 (eth0:1).  Now, how do I get those addresses to be
| publically accessible?  As in, how do I tell the FlowPoint to pass the
| traffic through?


I'm not quite sure I follow.

| 11.22.33.32 (obviously fake IPs...

why obviously fake IPs? these are valid IPs.
registered to the Defense Intelligence Agency.
are you a spook? not a spook? (bad idea to hijack
IP addrs from people that can make you disappear)

by "external" do really mean "internal"?

and by "publically accessible" do you mean "NATed to something
publically accessible"? (unless you work for the Defense Intelligence
Agency, you cannot[1] make 11.22.33.10 publicly accessible).

A typical config would have a real IP address (assigned
by the ISP) on the external interface (DSL interface).
The internal network would use private addresses (such
as 10.0.0.0/8 (or other block reserved for such purpose
(see RFC 1918) (not "borrowed" valid addresses)). The
router would be configured to do NAT:

    remote  setIptranslate on $ispname
