Question Problems getting Remote Desktop working at the same time as internet Sharing


Ok, I think this is probably the right forum for me problem.

First of all the configs :

Linux box:

Intel Celeron 333Mhz
Mandrake 9.2
Kernel 2.4.22-10

Windows box:

Intel P4 2.8Ghz Prescott
Windows XP

There are also other computers on the network, but they are not important for now.

I use the linux box to connect to the internet ( with an internal modem ) and it shares that internet connection with the other computers on the lan. It is also set up as the DHCP server. Security setting is standard.

I also want to be able to share files both ways between linux and windows, as well as use desktop sharing, I have downloaded VNC client for windows. I have used SWAT to carry out file sharing settings btw.

Now the internet connection sharing works fine, and I can even get the file and desktop sharing working, BUT not at the same time as internet seems like I have a choice of either internet sharing OR file and desktop sharing.

To get file and desktop sharing working I simply go to mandrake control center and tick the box that says allow "everything ( no firewall )" , and I am then able to use desktop sharing...and I think file sharing as well. but the internet sharing stops working. To get that going again I have to go through the Internet connection sharing wizard again ( possibly the wizard for setting up the network as well...its been a while since I have actually done memory is fading ), this then gets the internet sharing working again, BUT the desktop and file sharing stops again.

I want any computer on the lan to be able to access the linux box through desktop sharing so they can connect it to the internet when needed, and use the linux box to share that connection as well as sharing files on the lan, and i would like to do this without having a monitor, keyboard and mouse plugged in to the linux box.

I think thats all????
Did I miss anything? questions? answers?

Well for the Linux box to use ICS on windows, you'll need to tell the linux box the Gateway, DNS, and such I normally use static IP. Look at /etc/hosts

# hosts This file describes a number of hostname-to-address
# mappings for the TCP/IP subsystem. It is mostly
# used at boot time, when no name servers are running.
# On small systems, this file can be used instead of a
# "named" name server. Just add the names, addresses
# and any aliases to this file...
# By the way, Arnt Gulbrandsen <> says that
# should NEVER be named with the name of the machine. It causes problems
# for some (stupid) programs, irc and reputedly talk. :^)
(Taken from my /etc/hosts file.)

Remember to open the right ports for SMB. I know your using "no Firewall" bad deal. Only open the ports you need on the internal net work or Intranet, and lock down your ICS computer w/ a Firewall or just use the built in one If your using XP or 2000. Rings of security are much stronger than one big ring...

Start w/ a Class C network
your ICS box will have an IP of It is the gateway.
your Linux box can have an IP of, netmask
your ISP will give you a list of DNS or Domain Name Servers. Drop those into your Linux Box. Make sure it works. Next SMB
You have used swat so i will not go into it. If all else fails you can give your Linux box a second IP. You can then use that IP for you SMB configuration.
man ifconfig

My Linux box is my ICS box, I do use a firewall on the linux box, otherwise I can't seem to use ICS anyway, I am on my XP machine connected to the internet through the linux/ICS box.
ICS works fine, until I want to try and get "desktop sharing" or "file sharing" working, the only way I can seem to do this is by disabling the firewall.....but then the ICS stops working, so to get the ICS working again, I go through the ICS wizard, and then its fine, BUT then the "desktop sharing" and "file sharing" stop working
