ftp to gateway machine

[Brian Stults <bs7452@csc.albany.edu>]

Hi,

I have a computer connected to a cable modem, which then connects to a 
hub with two other computers on it.  I use ipchains to share the 
connection.  Connecting to anything external works great.  However, if I 
want to ftp from one of the internal computers to the gateway machine, 
it takes a long time to connect and then the transfer speeds are pretty 
slow.  I use 192.168.0.1 for eth1of the gateway computer, so that's the 
address I used for ftp.  It appears that even though I use 192.168.0.1, 
it still connects using my ip address for eth0 (which is connected to 
the cable modem).  I would have expected that going from my laptop 
(192.168.0.4) to the gateway would be really fast, especially since both 
ethernet cards are 10/100.  Am I misunderstanding something?  Any 
suggestions?

Thanks.
