No no windows involved here. We are developing application on Integra RDBMS, earlier
it was on SCO Unix and now on Red Hat Linux using ibcs module. Front ends are also
of Integra. So its all linux here. No windos as far as our critical applications are
concerned. Windows are only used for word processing on standalone machines.

Thanks a lot binand for this detailed explanation. I think I am slowly getting
what you are saying. Sorry I don't have any experience as far as networking with
routing and ip - forwarding hence I posted the question on the list. We might
go for this kind of setup in the near future not now.
