hello again,

   thanks from the beltWars crew for past help with our polyOrb dsa apps ...


   following is a 'problem' report, which i hope may explain better ...


best regards,

Rod.

 DESCRIPTION:

   we have the polyOrb dsa demo running well when it is run locally on an 
internal LAN.  
           (ie  using my 'local' ISP assigned IP address as the default ).

   polyorb.protocols.iiop.default_addr=203.220.152.76  -- my 'local' IP addr
   polyorb.protocols.iiop.default_port=2809

... for instance, works well.


   the 'local' IP address, however, seems not to be 'visible' to anyone 
outside of my local LAN.


   my 'remote' IP address is 'visible' to outside parties, but when i start a 
po_cos_naming server 
using that address, and then start the dsa example server,  i receive a 
polyorb.comm_failure.

   i suspect the trouble may be due to my local network config and possibly my 
polyorb.conf setup 
for each of po_cos_naming, the server and the client.

   also, within gdb, is seems  that the comm_failure is triggered by some kind 
of IP address 'circularity'.



REPEAT BY:

test program:   
   standard polyOrb dsa example (client/server )

topology:           
   server runs on my  'local'     LAN  connected to net via pppd
   client  runs on any 'remote' box   connected to net in any fashion.
   
   po_cos_naming  runs on local LAN, using 'remote' IP address
           'polyorb.protocols.iiop.default_addr=203.220.243.49'


expected results:
   usual result of running dsa example.



'polyorb.conf' for   po_cos_naming config =>

[iiop]
polyorb.protocols.iiop.default_addr=203.220.243.49
polyorb.protocols.iiop.default_port=2809



'polyorb.conf' for  server  config =>

hmm ... i guess thats about the lot for now ... 

please let me know if there is any extra info i need to include.
