Hi.
Your configuration looks fine.
The problem then should be with the network.
Try the following :
 From the Apache httpd server (command-line),

1) enter :
ping server2.ourlab.com

If you get regular messages showing that the ping packets are being answered, it's fine. 
If you get error messages, then you have a basic network problem accessing 
server2.ourlab.com from your Apache host.

(faked) example of a "good" answer :
PING server2.ourlab.com (192.168.20.1) 56(84) bytes of data.
64 bytes from server2.ourlab.com (192.168.20.1): icmp_seq=1 ttl=64 time=0.326 ms
64 bytes from server2.ourlab.com (192.168.20.1): icmp_seq=2 ttl=64 time=0.158 ms
64 bytes from server2.ourlab.com (192.168.20.1): icmp_seq=3 ttl=64 time=0.156 ms

Example of a bad answer :
- unknown host
- network is not reachable
etc..

2) If the above is fine, then :
enter :
telnet server2.ourlab.com 8009

It should at least connect (and may drop the connection right away), but the point is : is

it connecting ? If it is, you will get an answer similar to this :
Trying 192.168.20.1...
Connected to colin-int.
Escape character is '^]'.

xxx
Connection closed by foreign host.
