Check that the network is plumbed and up using

$ ifconfig -a

If you are only using the onboard 100Mbps network then you should see
a line like the following (substitute 172.16.0.100 for the E250 IP address);

hme0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index
2 inet 172.16.0.100 netmask ffffff00 broadcast 172.16.0.255

Do the other machines that you are pinging from reside on the same
subnet? If not it may be an issue with the there not being an
appropriate gateway in the routing table. Routes added manually
using the route command will not be retained on a reboot. Check this
using

$ netstat -rn

bash-2.05$ netstat -rn

Routing Table: IPv4

... the rest omitted for brevity.

You will need to for 'G' flags that identify gateway machines for
accessing different subnets.
