RE: [Xen-users] please help with xen networking with 2 ips

I don’t understand how you ‘have’ IPs from two different /8’s on the same physical network.  Please clarify.

Hi,

the networking just drives me crazy and it seems that i am missing something.

So here is my situation:
i have a server with 2 public IPs (85.214.1.230 and 81.169.1.81)
the dom0 is on:
ip 81.169.1.81
netmask 255.255.255.255
gw 81.169.1.1


i would like to have a domU with ip 85.214.1.230.

I tried everything routing, bridging.. nothing seems to work.

my dom0 config;
.
(network-script network-bridge)
(vif-script vif-bridge)





:~# route -n

any help would be highly appreciated
