I have configured sysctl.conf of the Lenny 64b (a virtualbox VPE) according to the wiki.

From all OS (including virtualbox, hosts, CT0), I can ping the CT (101), the router and internet
From the CT 101, I can ping every ip but the router and internet.

I don't understand why it cannot work.

The main Ubuntu 64 bit has bridge, each Virtualbox use bridged network.
CT0 use vnet.

Can you help me, please?
