Hellow
i'M testing Proxmox and have next problem, i create CT witch have veth.
use default settings.
In CT machine use dhclient eth0, but don't get IP adress
in proxmox host don't have ip in veth101.0.

cat /etc/network/interface
Code: 
iface lo inet loopback

auto vmbr0
iface vmbr0 inet static
    address 192.168.1.210
    netmask 255.255.255.0
    gateway 192.168.1.1
    bridge_ports eth0
    bridge_stp off
    bridge_fd 0


#auto venet0-00 
#iface venet0-00 inet dhcp
ifconfig

Last edited:
set up DHCP server for vmbr0 (192.168.1.0/24) or do you use DHCP from eth0 incoming port ?

p.s. no need any settings for veth101.0
 
yes use dhcp for eth0, but when don't use is this same problem.
vmbr has static configuration ip
Proxmox is installed in virtualbox maby multi visualisation create problem
 
in nano /etc/sysctl.conf
Uncomment and change to 1 this parametric, now work.
Code: 
# Uncomment the next line to enable packet forwarding for IPv4
net.ipv4.ip_forward=1


thanks for help
