[ibasaw]

Hi,

new on proxmox, got version 3

I created a CT with template debian 64

in my guest CT debian, i cant ping internet or do an apt-get update

Here my conf

/etc/network/interfaces

auto lo
iface lo inet loopback

iface eth0 inet manual

iface eth1 inet manual

auto vmbr0
iface vmbr0 inet static
    address xx.xx.xx.205
    netmask 255.255.255.0
    gateway xx.xx.xx.1
    bridge_ports eth0
    bridge_stp off
    bridge_fd 0

route -n

route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.0.100   0.0.0.0         255.255.255.255 UH    0      0        0 venet0
62.210.0.0      0.0.0.0         255.255.0.0     U     0      0        0 vmbr0

How did you configure the network on the guest?

Hi,
you use venet or bridge mode for CT networking? If bridge mode, you must simply define an normal IP-connection inside the CT (iface eth0 ...).

BTW. you netmask don't fit: netmask 255.255.255.0 != "62.210.0.0 0.0.0.0 255.255.0.0 U 0 0 0 vmbr0"

i use venet with the ip adress 192.168.0.100

i think the proxmox CT installer did the job to configure the guest automaticaly

i do nothing special on the guest
