Subject: iMac cannot access any IBM i based internal servers by IP and port

So David can run me off to the iMac list if this doesn't seem to be a midrange issue.....

I have the most unusual issue and since I am a total noob in the Apple world, I am not sure if it is a setting on the iMac or an issue with the IBM i itself. Here is the issue:

I have a laptop (windows), my IBM i, and an iMac all on the same physical network and subnet. Laptop is at 10.0.10.24, iMac at
10.0.10.26 and IBM i at 10.0.10.205.

I have multiple web sites hosted on the i with addresses NAT'ed and port mapped by a Windows ISA Firewall. A specific example is opensourceoni.com. That domain points to my ISA server and ISA maps that to the internal address of 10.0.10.205 and port 9095 which is running Tomcat (yeah, I need to change that default page) .

On my laptop, internally, I can hit either opensourceoni.com OR I can hit 10.0.10.205 port 9095 and I'll get the web page. On the iMac I can ONLY hit the external site URL. If I try 10.0.10.205:9095, Safari eventually times out with a "Safari Can't Open the Page" error.

If I fire up Tomcat on my laptop at port 9080 , I can then go to the iMac and type 10.0.10.24:9080 and bang! I am on the Tomcat page served by the laptop. Checking to see if it is a *NIX issue, I pointed the iMac at a server that runs Asterisk and FOG and both web interfaces will display. If I point the iMac to the HTTP Admin page on the IBM i, it times out with the same error! The iMac CAN get to both the VIOS and AMM web pages. So there is something fishy about the iMac and the i...

Wondering if this was an Apple conspiracy, I went ahead and tried the same internal, i based web sites on my iPhone. They also won't display.

So the question at the bottom of all this is: Have any of you Mac folks run into this? Is it that Apple hates IBM or is it something about Safari on an Apple OS? Safari in windows displays all of the web sites just fine.
