Ok, so I know that there has been a
couple of questions asked recently about NAT in Xen,
but even after going through those, I still can’t get this to work.
I’m still new to Xen, but I
believe what I want to do should be easy, and I can’t figure it out.
The basis behind what I’m doing is as follows: I am setting up a server to host several
different things for me, each in it’s own domU, mailserver, webserver, etc. Only
problem is that I only have 1 static IP from my ISP available, so I need to
share them all behind a NAT. I plan on
using my dom0 as a firewall/NAT for all my domU’s.
I originally setup my domU’s
under the bridged mode just to get them up and running and make sure everything
works. It all worked well and I was able
to access the internet perfectly. So
then I changed it over to the nat scripts that come
with Xen and now I can’t get anything
working. I am using FC5 as my domU and my only domU right now
is a FC4 system. I have tried to use
this link below even though it’s for debian,
but I still can’t get it to work.

Obviously some of those paths (namely the ones for the network configuration
files) are different between Debian and FC4, but
those only come into play after the networking is actually working, when you
want to setup the port forwarding. I’m
not even able to ping out to anywhere, even to the dom0.
On this system I installed Xen from the FC5
rpm’s (via yum).
I don’t get any errors, on any of the configurations,
I just can’t get the domU to be able to ping
anything.
Any help would be appreciated!
