Now it's working.
But I don't know how to enable ifenslave at boot?
# ifenslave bond0 eth0 eth1
Can I put that in /etc/network/interfaces?
My howto: (Is it correct?)
# apt-get install ifenslave
In /etc/modules i put "bonding".
In /etc/network/interfaces I put this:
auto bond0
iface bond0 inet static
address 1.2.3.4
netmask 1.2.3.4
gateway 1.2.3.4
