IP Network Design?

» close window

The Question is:

 
Hey,
 
You really know your stuff, guess thats why your the wizard.
I on the other hand, dont know my stuff, but here we go.
 
Digital Alpha Server 1000 4/233
vms v.5.1-2
decnet
smarterm interface
 
I am researching the possibility of using my Win Nt server to allow access
to our alphaserver from a remote location.To provide security through the
firewall and such.Only 4 users from the remote location.
 
Noticed a few things from FAQ.
 
no support for RAS with OVMS.
i would need to upgrade decnet to decnet plus for TCP/IP.
 
But would things be different if i was using DSL or T-1 for access?
Is any of this possible with our version of VMS v.5.1-2?
 
Would i be better off using a multiplex unit to tie in remote access for
a direct connection to alphaserver?
 
I cuurently run the Windows end of this companies system.
Our VMS is handled by a outside source.
Is this to large off an undertaking and to complex a system to mess
with?
Im thinking i might have better reliability going direct.
 
Thanks for your help

The Answer is :

 
  Probably the easiest approach would be to set up an IP tunnel, and
  route an IP connection from the client through the firewall and in
  to an IP router on the protected network and from there along to the
  OpenVMS system(s).
 
  Generic networking questions and IP network design questions are
  rather outside the usual charter of the OpenVMS Wizard.  This
  particular question is best routed to your network security wizard
  and/or to the folks in the Compaq Services organization, as these
  resources can help you configure your network and your firewall
  and your systems to meet your particular needs.
 
  DSL and T1 are discussions of bandwidth, and of the controller(s)
  (host-based, network-based, etc) necessary for the connections.
  T1 has a defined bandwidth of 1.544 megabits per second.  DSL
  has a theoretical maximum rate of 8.448 megabits per second and
  an observed maximum of 6.1 megabits, but most connections will
  provide from 1.544 to 512 kilobits per second downlink (network
  to host) and 128 kilobits per second uplink (host to network).
  Depending on your local telephone network and your local telephone
  provider, you may or may not be able to acquire DSL, and you may or
  may not be able to acquire anything approaching the theoretical DSL
  maximum throughput.
 
  Point-to-point dialup (modem) connections are generally limited to
  56 kilobytes per second, possibly with asymmetric bandwidth.
 
  Depending on distances and bandwidth, fibre or ATM may be an
  appropriate solution.
