I can't ping to freebsd machine

[bsdnewbie]

Hi,

On the same lan i have freebsd and windows machines.
FreeBSD machine has two network cards:

ifconfig_re0="inet 192.168.0.2 netmask 255.255.255.0"
ifconfig_re1="inet 192.168.0.3 netmask 255.255.255.0"

Then i trying to ping to freebsd machine from windows client (which
has 192.168.0.4) , i've got
request time out.
C:\>ping 192.168.0.2

Pinging 192.168.0.2 with 32 bytes of data:

Request timed out.
Request timed out.
Request timed out.
Request timed out.

Ping statistics for 192.168.0.2:
Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),

Is it normal, that i can't ping to bsd machine?

thank you for your answers...
