Ummmm 192.168.0.254 isn't a broadcast address.  Assiuming you have a netmask
of 255.255.255.0 the broadcast is: 192.168.0.255.

Disconnect from the 'Net
Anyaway Dump and/all ipchains/iptables rules you have.
ipchains -F; ipchains -X
iptables -t filter -F          #I think I still use ipchains.

ping -c 2 127.0.0.1
ping -c 2 192.168.0.1
ping -c 2 192.168.0.X   where X is the ip of your second box.

If one or more of those file then:
email us the output from:
/sbin/lsmod
/sbin/ifconfig -a
/sbin/route -n
And the error you get from ping.
