Thanks Sean,

I've relayed this on to our network vendor support folks.

That is interesting that what you would THINK work one way, works another
(the port traffic deal) !

We had the same problem except with 594 instead of 494.  FYI, the access
list in our case did NOT stop traffic on those ports.  Cisco doc said it
only stopped traffic TO the router not THROUGH the router.  Useless.  YMMV.

The above two rules I quoted are probably your problem.  I think either the
AS/400 or the Perle may ping before attempting to connect.  I found no docs
to support that, but removing that block solved our problem.

A better bet is to start logging packets somewhere (somewhere depends on
your network setup, I used our firewall) and get the computers cleaned and
patched.

Good luck!
