Under some circumstances I experience very long delays connecting with
FTP to my linux RH 6.0 machine from my Win98 box.

Please read slowly as this gets hard to explain :-)

The win98 box's TCP properties have the linux box as a gateway. 
This was done to allow me to setup Masquerading as per the
IP-Masquerading HOWTO. (and it works)

The Linux machine is running Wu-ftpd (Anon-FTP is not installed) and
the /etc/hosts  file specifies my Windows box as winbox and my linux
box as linuxhost

127.0.0.1     localhost   localhost.localdomain
192.168.0.1   linuxhost   linuxhost.mydomain
192.168.0.2   winbox

The critical factor seems to be the Linux machine's /etc/resolv.conf
file which is setup like this using the altered IP addresses of my
ISP:

   domain my.isp.com
   nameserver 203.11.11.1
   nameserver 203.11.11.2
   
This works great for my PPP connection to the net and while I have my
ppp0 interface up, I have no problem connecting to my Linux box from
the Win box using FTP.

This stops once my ppp0 interface is down. I can still FTP to the
Linux machine but this sometimes takes up to a minute.  

BTW the Win machine has no problems Telnetting to the linux machine at
any time and fast too.

So I experiment with changing my /etc/resolv.conf back to its default
format after installation which is like this:

   search mydomain          #  domain name of my Linux box
   nameserver 192.168.0.1    #  Linux machine's IP
   
This allows me to establish an FTP connection to the linux machine
without a problem but this will wreck my PPP setup for my ISP

I've tried to create a merged version of /etc/resolv.conf using my
linux machine's IP and then my ISP's nameservers but this too prevents
a timely FTP connection while my ppp0 is down.

So what could be going wrong? I don't understand the whole resolver
process very well and I understand it less the more I read
documentation.
