RE: [Xen-devel] Problems

["Jaswinder S. Ahluwalia" <jahluwal@xxxxxxxxxxx>]

Hi,

Thanks for the info. So I did what was said in the past few e-mails you have
sent me and when I ran xen_nat_enable I got a message about "iptables,
command not found. Have you built netfilter?"

So I installed iptables from the mandrake disk that I have and now its
saying "iptables: invalid argument. Have you built netfilter?"

Thanks,
Jas

What do you mean by remotely? From another real
computer on the LAN?

Both 169.254.X.X and 192.168.X.X are private IP
addresses. If you want to access these IP addresses
from outside, you have to set up NAT rules in the gateway.

e.g.:

Your Domain0 has a real physical network interface
which is connected to the local network with IP address
A.B.C.D and you use 169.254.1.0 as the IP address
for Domain0 virtual network interface.

Newly created domain 1 has 169.254.1.1 as the IP
address for virtual network interface, and 169.254.1.0
as gateway.

Now, you want to visit domain1 from another real
physical computer on LAN, whose IP address is
A.B.C.E

Then, you must insert NAT rules in Domain0. As
a result, when A.B.C.E connects to A.B.C.D, port
9991, Domain0 forwards the packet to domain1
(i.e. 169.254.1.1)


In short, there is no difference between using
169.254.1.x and 192.168.1.x, but our current
'xen_nat_enable' hard codes 169.254.1.x,
so it's more convenient to follow suit.

You can find further online information on NAT.
