ISDN, Cisco 760 Router and SME Server...
« on: May 22, 2002, 08:58:18 PM »
I'm trying to add the SME server to our company network, but am having trouble trying to connect to the internet.  

We have a 128-ISDN connection (AT&T Canada) which currently connects to a Cisco 760 router which then connects to our hub serving a 12 computer office network.

I'm trying to connect the server between the router and the hub, and although our network recognizes the server (all computers running Win2000 - no current server), I can't for the life of me connect to the internet from the server.

I've set-up the server as 'dedicated' due to the router, but it suggests selecting 'dialup' with an ISDN connection - is it possible to dial-up to the ISDN network with just an ethernet card and eliminate the router?  (my dumb question of the day...)

I'm probably just not getting the right gateway IP or something, but I'm clueless at this point.  Any input would be greatly appreciated...

Hello Dave.
Are u using the server in "Server and gateway" mode? If you try to use  two nics to connect it between router and hub i think that you have to use it in server and gateway mode. i think that router it self will connect that network to internet if the data is coming to it.

Yeah, I have it in Server/Gateway mode.  I've tried pretty much every configuration I can think of, although I'm a complete newbie at this stuff so I'm sure I'm just not fully grasping the overall picture.

I tried something else though - I by passed the hub, and connected the router directly to a computer - there's no network connection by doing it this way either, so does that mean that the hub has something to do with this whole connection thing?

Thanks for the help....

Dave, you can't set up your server in server/gateway mode. Your Cisco router is the gateway in your corporate network.

Set the server up in server only mode and config the Cisco router as the gateway and connect the server to hub (only one NIC i use)

Thanks!  You're absolutely right!  

I have it in Server-only mode now, but how can do I identify the server so it can be accessed by VPN?

Hmm, what is vpn in your terms. A VPN connection between two SME boxes, or general VPN access for remote users into your corporate network.

Hey Dave

As far as I know you only can etablish a vpn connection between two SME boxes, haven't tried it yet. - Maybe I'm wrong, but I understand that your fine box can etablish a LPT2 tunnel to another fine SME box, and thats it!

If you want general vpn access I think you have to look at some vpn concentrators, like the small small Cisco Pix firewalls. With these small boxes you can etablish a stronger 3Des encrypted tunnel for your users (W2K etc.) you just have to install the cisco vpn client.

Thanks for your input.  It's been helpful.

However in section '10.2.2. PPTP' of the User's Guide, it leads me to believe that a tunnel can be established between the server and individual clients.  Am I understanding this wrong?

Here's a more specific quote from that section of the User Guide:

"Microsoft's PPTP implementation is widely used in the Windows world to provide remote access across the Internet. If you have a remote Windows system (for instance, a laptop or a home computer) that has access to the Internet, you can also access the information stored on your server."

Yep, you're right. Just go on, I think there can be some issues gaining access from Internet to your SME box. Is your PAT configured right in your Cisco 760 and so on.

No, and to tell you the truth, I know nothing about that darn router, and  don't know where to start.  Can anyone point me to information on configuring a router?

Does anyone have experience with PPTP with the server located behind a firewall?
