[SOLVED] ARP does not resolve MAC address of hosts on the same subnet

Hi,

I just changed my CentOS server from DHCP to static IP address. After the change, I cannot ping other hosts on the same subnet. (I can ping the CentOS itself).

The IP address of CentOS is 192.168.0.202.

After pinging 192.168.0.106 (106 is on and other host can ping it), arp -a shows
? (192.168.0.106) at <incomplete> on eth0

It looks ARP cannot resolve MAC address of hosts 192.168.0.106.

Please help and thanks in advance.

Problem solved.

The problem was that the centOS was running in VMware and the VMware network adapter was configured as NAT. After I change it to Bridged, it works.
