 Subject:  Mapping through Multiple external IP
 Date:  Wed, 17 Jan 2007 15:28:49 -0800
I have m0n0wall 1.2b0 (Jun19, 2005) installed and I'm trying to get NAT
working with a secondary IP address and having problems!


(Using bogus IP numbers...) 


To describe this a little better, I have the WAN set as static with IP
address, GW:  So I have these IPs available
for NATing to internal servers. (the firewall) (app1) (app2) (ftp) (app4)


So I added to ServerNAT.

Added firewall NAT of WAN, TCP, FTP,, FT which also
created a Firewall rule to allow incoming TCP on 21 from any.  

I selected the interface as the External Interface in

NAT autocreated the rule for me.


I am unable to connect to the FTP server from an outside machine through
the interface.

(I tested my FTP server by setting up NAT through my main IP address
first before trying this and it did work fine.)


Some additional points:

 * I did not reboot my firewall machine.

 * The address was being used by another machine connected
to the same hub, but I disabled that machine's interface before trying
all of this.


I've tried all kinds of settings in m0n0wall to try to get it to
actually grab and route stuff on this secondary IP, but it just doesn't
seem to ever actually take ownership of that IP!


Is there something I'm missing?  Any ideas?
