[ILUG] Virtual DHCP network

[David Pintor]

Hi,

I'm trying to configure a DHCP server in a Fedora virtual box that will
provide ip addresses to other virtual boxes, so far with no success.

These are the steps that i'm following (more or less), if anyone can put me
in the right direction or send me a good link to do this that would be
great. Been googling for 3 days, but no joy...

- Basically, the DHCP server gets the IP "bridged" from the host, so it will
be a 192.168.1.x, same range that the host.
- What I want to do (or I think i need to do) is put my virtual network in a
different IP range (ie, 192.168.100.x), so it doesnt interfere with the rest
of pc's in the house.
- So I thought i might just NAT the address from the host and not bridge it?
And then i get a 10.0.2.x IP in my virtual box, which can see the internets
(cool). The ideal would be to have a static IP here (as it's going to be the
dhcp server), something like 10.0.2.1 would be the ideal. However when I
change the ip address, the box can't see the internet anymore (ping to
google fails).
- I've tried also creating another interface (tun0) on the top of eth0 but
as soon as the Ip changes, no internet acces either...

Hope this makes sense... I think it might be some problem with the routing
table, but not sure. I am unfortunately quite a newby in network stuff and
all this seems like a highly complex task to do, even though it might be
straight forward enough... Any tips are welcome. I might have forgotten to
post important information too - if so please ask, i didnt want to make this
email too long.

Thanks in advance and happy christmas to everyone!!
