I have the following setup:

My router - 192.168.0.1
My host computer (Windows 7) - 192.168.0.3

And Ubuntu is running as virtual machine on the host. VMWare network settings is Bridged mode. I've modified Ubuntu network settings in /etc/netowrk/interfaces, set the following config:

iface eth0 inet static
address 192.168.0.220
netmask 255.255.255.0
network 192.168.0.0
broadcast 192.168.0.255
gateway 192.168.0.1

Internet works correctly, I can install packages. But it gets weird if I try to ping something I get this:

PING belpak.by (193.232.248.80) 56(84) bytes of data.

I think even more interesting are the results of pinging the router itself:

stonerain@ubuntu:~$ ping 192.168.0.1 -c 1
PING 192.168.0.1 (192.168.0.1) 56(84) bytes of data.

rtt min/avg/max/mdev = 6.644/6.644/6.644/0.000 ms

But if I set -c 2:

...

Pinging host machine on the other hand works absolutely correctly: no DUPs, no errors.

What seems to be the problem and how can I fix it? Thank you.
