[coLinux-users] Routing problem to coLinux from other computers

[John F. <J.P...@as...>]

I have set up coLinux using 0.6.1 and the Fedora Core 1 
distribution. I am using Tap and Internet Connection sharing.  All 
this works well on two installations, one Windows XP and one 
Windows 2000. I also run vncserver and samba on the Fedora 
coLinux and can see these on the PC hosting coLinux.

I would like to enable these services on another PC in the same 
workgroup as the host PC, and I have been unable to discover how 
to configure the routing in the host windows XP PC to do this.

Example

Real network
==========
HOST PC: 192.168.123.2   (Windows XP)
Another PC: 192.168.123.1 (Windows 95 OSR 2)
Gateway: 192.168.123.254 

coLinux Network
=====
TAP Gateway 192.168.0.1
coLinux 192.168.0.40

ICS enabled on the Real network on the HOST PC.

coLinux can ping to 192.168.123.1

the other PC cannot ping to 192.168.0.40 or 192.168.0.1

I think that one way to overcome this problem would be to enable a 
NAT service and allocate to the coLinux an IP number in the series 
of the real network. e.g.

192.168.123.40 <=> 192.168.0.40

The problem is that I cannot find out how to do this.  There are a 
number of items in XP e.g. RRAS, netsh, route, which are just not 
intended for ordinary people to know about. We are expected to 
use tools which assume we want to do something different.

I found this web site which suggests modification to the Regstry 
setting for IpEnableRouter and I have applied this to the XP 
computer but it is not the complete solution.

There is also some discussion of the problem at this page on the 
wiki

Any help will be appreciated and I'll put the solution to this onto the 
wiki.
