Hello Proxmox users and developers :D.

Sorry for post this, but I really need your help to solve this. I have a problem when I try to move from a segment /29 to a /30 one.
Please take a look of this

Code:
root@proxmox:/media/western/FalloProxMox# netstat -r
Kernel IP routing table
Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface
159.xx.237.136  *               255.255.255.252 U         0 0          0 vmbr0
192.168.1.0     *               255.255.255.0   U         0 0          0 eth1

Code:
root@proxmox:/media/western/FalloProxMox#[B] ifup vmbr0[/B]
[B]device vmbr0 already exists; can't create bridge with the same name[/B]
[B]run-parts: /etc/network/if-pre-up.d/bridge exited with return code 1[/B]
SIOCADDRT: No such process
Failed to bring up vmbr0.

And of course I try the classical reboot.

Code:
root@proxmox:/media/western/FalloProxMox# /etc/init.d/networking restart
Running /etc/init.d/networking restart is deprecated because it may not enable again some interfaces ... (warning).
Reconfiguring network interfaces...device vmbr0 already exists; can't create bridge with the same name

done.

And my ifconfig

And I look up at the /etc/nerwork/interfaces and looks like a new proxmox install.
I dont know if its problem of my new segment and proxmox, or I so dummy to see something wrong with the broadcast adress.


Thanks a lot for the proxmox project!!!!.

SOLVED: My mistake, it was a problem whit my gateway adress, solved when I checked my route -n and I saw that I was using the broadcast adress like a gateway :rolleyes:.
