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

[Pete Helgren <pete@xxxxxxxxxx>]

They sure act like it.... but the iPhone has no SIM card in it so it 
only uses the wireless here in the office and the iMac has an Ethernet 
cable to it and I turned off the AirPort wireless adapter.  They both 
are getting IP addresses, subnets and gateways that are consistent with 
the internal network.

The really weird part is that I have an Apache HTTP instance and a 
Tomcat instance on the Windows server I run as well as a Tomcat instance 
on my laptop.  So I can hit the internal address of the HTTP server and 
the Tomcat server on the Windows box as well as the Tomcat instance on 
the laptop, all using internal addresses but I CANNOT hit the internal 
address for the HTTP and Tomcat server on the IBM i.  In fact, trace 
route can't find the host.  That pretty much indicates a routing issue 
(I think) with the i.  The default gateway on the *DFTROUTE points back 
to the internal address on the firewall which is where it should point 
in order to get to the Internet.

It is pretty bizarre and must have something to do with the way routing 
works on the Mac (?).  Somehow, it is having trouble seeing the i but no 
trouble seeing any Windows or Linux box.
