I have ubuntu server 12.10 on vmware.
When I have NAT network configuration I get ipv4 address (checking ifconfig eth0).
With bridged connection I get only ipv6 connection, but I need an ipv4 connection as well..
What should I do?
With a bridged connection VMware does nothing for you in regard to addressing. It should work as if the VM is connected directly to the ethernet. If your ethernet has a DHCP server and you have the VM configured to use DHCP then it should just work. If your ethernet does not have a DHCP server then you need to configure IPv4 manually.
