unable to access machine on same router


I have a linux box (Ubuntu Breezy) which, I suspect, I may have messed up the routing table on. Unfortunately, I have no idea how those things work, so I am going to put a little information here and ask that you guys give me a little advice.

The machine I am trying to access, and OpenBSD box, is alive and accessible by other machines on the net. When I try to ping it from my Ubuntu box, I get replies such as this:

PING squee.dnsalias.com (199.237.163.175) 56(84) bytes of data.
From 199.237.162.60 icmp_seq=2 Destination Host Unreachable
From 199.237.162.60 icmp_seq=3 Destination Host Unreachable
From 199.237.162.60 icmp_seq=4 Destination Host Unreachable
...

My Ubuntubox's routing table looks like this:

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
199.237.162.0 * 255.255.254.0 U 0 0 0 eth0
default 199.237.162.1 0.0.0.0 UG 0 0 0 eth0

The thing that makes me wonder, is that when I run a traceroute it comes up like this:

traceroute to 199.237.163.175 (199.237.163.175), 30 hops max, 38 byte packets
1 199.237.162.60 (199.237.162.60) 3003.092 ms !H 2999.803 ms !H 3000.391 ms !H

it never even gets past my own IP address (199.237.162.60).

Again, I really have very little idea how the routing tables and stuff works, but does this seem abnormal to anyone who does? If so, do you have any suggestions to remedy it? Thanks for your advice.
