Re: [Xen-users] network-route and vif-route setup help
Sorry about the delay everyone. I had some email troubles for the last week.
its all
back to normal now.
Jason: The subnet for all my ip's is 255.255.255.255
Yura Pismerov: If i use 1:1 NAT, then from inside the domU's i will have to
have a
different IP's then outside. i would like to have the same ip's as outside if
thats
possible.
Andreas Jellinghaus: I never heard of point to point. I don't know what it is.
All the
information i could find in google wasn't too helpful, lots of ppp or PPPoE
stuff. I did
find it in ifconfig man page though. Is there a howto anywhere? especially with
xen?
Or maybe you could write a small howto maybe?
Steffen Heil: with 1and1 i get disconnect when i start xend. Which means dom0
doesn't
even get a chance to work. So all the domU's don't work either. I think xend
start the
bridge with FFFFFFFFFFFF as MAC and then does a transfer. I think thats what
kills the
connection. the switch drops the connection whenever it seems a different MAC.
I have
read about ebtables though. reading as many howto's on it as i can.

what i don't understand is the "ip r" output. the src part. In the config the
src ip
address wasn't specified. So does this get generated automatically? or did you
mean
public.dom0 for the ip= (not the one in vif)?
Once again, thanks to everyone who replied.
And sorry for the delay in reply, totally unintentional.
