This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
Another charge I have is to connect an Appache server (in the DMZ) to JBoss (on the inside). I'm not a firewall guy (again, just an app developer), but someone at work figured they're all the same (ha!). But I'm supposed to know how to make the http server talk to JBoss, including specifying ports to open.
That would be great if you have a lab that does that!! I actually had SSL working between the Appache box and the web container, but it broke when they moved the Appache box into the DMZ :-(
