I have a m0n0wall router
a VMWare workstation running ubuntu
a windows 7 workstation running the VM

The ubuntu hostname is "renraku" From the windows machine I can't resolve dns automatically for this host. For example, when I

ping renraku
Ping request could not find host renraku. Please check the name and try again.

However nslookup seems to work

nslookup renraku
Server:  m0n0wall.local
Address:  192.168.123.254

Name:    renraku
Address:  192.168.123.248

I don't get how to have ping to work with hostnames. The main goal behind this is to have my web server to work with hostnames instead of ip addresses

EDIT :

ping 192.168.123.248 works
