Hi,

I just started with OpenVZ and can't get networking to work. My setup looks like this:

[Internet]
   ^
   |
  eth0
   |
   v
[OpenVZ-Server (Public IP)]
   |vnet
[VE (Private IP)]

I can Ping the servers IP from the VE and the VEs private IP from the Host, ssh also works between them, but the VE can't acces the Internet. Probably a routing problem but I'm stuck :(

The routing tables:

Host:

crct master ~ # route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.0.100   *               255.255.255.255 UH    0      0        0 venet0
77.37.6.0       *               255.255.255.0   U     0      0        0 eth0
loopback        *               255.0.0.0       U     0      0        0 lo
default         77.37.6.1       0.0.0.0         UG    0      0        0 eth0

VE:

oldserver ~ # route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.0.2.0       *               255.255.255.0   U     0      0        0 venet0
127.0.0.0       *               255.0.0.0       U     0      0        0 lo
default         192.0.2.1       0.0.0.0         UG    0      0        0 venet0

Issuing the route command on the VE takes some time. The VEs /etc/conf.d/net looks like this:

config_venet0=(   "192.168.0.100/32" )
routes_venet0=(  "-net 192.0.2.0/24"  "default via 192.0.2.1" )

Note the default GW. Is this right?

Both Host and VE run on Gentoo.

Most common causes for this are deny rules in your forward chain or packet forwarding disabled on the hardware node. Please check and let us know.
