Connect: Network is unreachable

I relocated our office webserver and changed the IP address, gateway, and mask. After booting it at the new location. I cannot get to any outside host, nor can I get to this host from the outside. Odd thing is, I had a RaspberryPi connected to this same IP at the same location for a couple of days as a place-holder waiting for the "real" computer and everything worked fine. I'm kind of clueless as to where to start. It's probably something simple ...
$ ifconfig eth0
eth0      Link encap:Ethernet  HWaddr 00:C0:A8:7B:93:1F
          inet addr:  Bcast:  Mask:
          inet6 addr: fe80::2c0:a8ff:fe7b:931f/64 Scope:Link

I can `dig` and the nameserver returns an answer, but I can neither ping or ping its IP, or ping any IP. For example:
$ host has address mail is handled by 10

$ ping
connect: Network is unreachable

$ ping
connect: Network is unreachable

Why is the network unreachable? I don't know if I'm having a hardware problem or just a simple/stupid configuration issue. Firewall is down.

more info, this external nmap says the host is up, but all 1000 scanned ports are blocked!? Firewall is down. I believe I was able to get into the RaspberryPi similarly configured a few hours before. I need ideas!

The traceroute finishes with your gateway as the destination, it doesn't however finish when using the server as destination, might be a routing thing? Is the configured with the correct settings?
Netstat -rn,
Where is your name service? It is getting information.

You have two IPs on this system.
Ping/icmp ...  Try. Telnet 80 is the connection established?

Double check your ip/netmask

The block can be on the carrier/router to which your system is plugged in.

Iptables -L
rebooting the router fixed the issue?

Figured it out. A sharp eye would have noticed a space between "GATEWAY" and "=" in line 13 of my rc.inet1.conf posting. Certainly it took me all day to notice it. If fact, when rebooting for another test I saw something about "invalid GATEWAY in line 48".
