Re: cannot ping anything

thanks, but the defaultrouter line was already present in my 
/etc/rc.conf.

Check your /etc/rc.conf for this line:
defaultrouter="192.168.1.1"
add it and reboot if it is missing

Yesterday I placed an HD with Freebsd 5.3 release in a Dell Dimension 
L800CXE.  It booted properly. ( since it's running a generic kernel 
with only a name change)
However I could not ping anything inside or outside the LAN.
Ex:
ping google.com
ping: cannot resolve google.com: Hostname lookup failure
ping 192.168.1.1
ping: sendto: No route to host
I tried several addresses inside the LAN, 127.0.0.1, localhost, 
192.168.1.128, and all gave the same result.
I was previously using this HD in another machine to test IPF, with 
NAT also, and it worked peerfectly there.

So just to be safe I erased the contents of /etc/rc.conf, and then 
used sysinstall to bring up my NIC.  I  chose NO for IPv6, and YES 
for DHCP.
That seemed to work correctly, just to be sure I ran ifconfig:
dc0: flags=108843<UP,BROACAST,RUNNING,SIMPLEX,MULTIPLY> MTU 1500
        options=8<VLAN_MTU>
        inet 192.168.1.128 netmask 0xffffff00 broadcast 192.168.1.255
        ether 00:80:ad:81:1a:9f
        media: Ethernat autoselect (100baseTX)
        status: active
plip0: flags=108810<POINTOPOINT,SIMPLEX,MULTICAST> mtu 1500
lo0: flags=8049<UP,LOOPBACK,SIMPLEX,MULTICAST> mtu 1500
        inet 127.0.0.1 netmask 0xff000000
Still, things are looking good; so, I go to another box, log into my 
router(192.168.1.1), and I can see the MAC address of the BSD box on 
my router.

However, I still get the same results when I ping as I did above.
Then I checked the routing tables:
netstat -r

The output of netstat and ifconfig aboe are from today.  I began 
having this problem yesterday, and left the box on over night.  
Yesterday's output was different in that the BSD box had a different 
IP address, 192.168.1.122.  That is fine I understand that the box is 
communicating with the router and negotiating leases when they 
expire.  However, why has the gateway to 192.168.1.1 changed from 
link#1 to the MAC address of my router.  I am certain that if  I 
restart the computer that same gateway will revert to link#1.
The my questions are:

How do I get the system to see others in the network, and vice-versa?

What should the gateway for 192.168.1.1 be?(which also happens to be 
my routers address)

I am hoping it is something simple.  I could just as have easily 
reinstalled the system and started from scratch, but I wanted to know 
how to solve this problem.
Other info that might help:
less /etc/rc.conf
ifconfig_dco="DHCP"
hostname="fw.company.com"
defaultrouter="192.168.1.1"
less /etc/resolv.conf
search carolina.rr.com
nameserver 24.25.5.60
naemserver 24.25.5.61
less /etc/hosts
::1                     localhost.company.com   localhost
127.0.0.1               localhost.company.com   localhost
Thanks in advance
