Routing or VNC Problem?

[Mike Morrell]

  Yeah, tried this.  It too gets connection refused.  I just can figure out
why I can ping across the subnets and use the web interface with no problem
but then have trouble telnet'ing to the port and using the VNC client.
Maybe I will try them all again and make sure I did not miss something.
