==================

I have an NT wkstation connected to internet using ethernet at work. (it has an SMC EtherPower card & a faxmodem)

Can i use RAS to dial in from my home computer and use my office computer as a "gateway". i know through RAS i can access the LAN in my office. Can this functionality be extended to accessing internet ?

if yes, then can somebody tell me how ?
(i am willing to adjust my points, if needed :-)

Thx.

It's pretty easy.  Do you use DHCP at work for IP addresses or are IP's static?  You will also probably need administrative access to the NT Workstation to configure (although I'm not sure).  Also, many companies prohibit these sort of connections to the network as it's a security issue, so be sure you have the green light from someone.  

Under Network Properties, click the services tab, and go into the properties for the Remote Access Service.  Make sure the port being used it configured to recieve calls.  

Click the Network Button and configure TCP/IP protocol.  You will want to click the button "Entire Network" under "Allow remote TCP/IP clients to access:"

If you use DHCP to assign IP addresses, then this is all the configuration you will need to do.  Otherwise enter 2 IP addresses for the machine to use for clients (I believe you need to enter at least 2 addresses).

Now go into User Manager and make sure the account you are going to use to dial in has remote access permissions.

It's relatively easy to configure, and works pretty well.  You may have problems on some 95 clients connecting, if so, turn off software compression in the workstations TCP/IP properties and it should work.

Good luck

Imar,

Thx for your answer. actually it's really easy. (i figured it out later.) but the problem i have is that i don't use DHCP and i have got ONE extra IP address that i can use. (but NT insists that it needs two !)

Since NT Wkstation allows only one connection, do you know whether there is a workaround and specify only one IP address.

also, if i enable NetBEUI, IPX/SPX does it really slow down the computer ? would you mind to comment

Connect further...control easier

With the ATEN CE624, you can now enjoy a high-quality visual experience powered by HDBaseT technology and the convenience of a single Cat6 cable to transmit uncompressed video with zero latency and multi-streaming for dual-view applications where remote access is required.

NetBeui and IPX will only let you access to your local network and not the internet.  If your network goes across routers, then you need to use IPX as NetBeui is not routeable.

You need 2 IP's unfortunately and there's no way around this.

Good luck

Thx, i've increased the points and graded your answer.

i've got another question regarding RAS phone line.
Can RAS be set to respond only after a given # of rings.

As it is, RAS picks up the call right away and thus i couldn't use the telephone line for any other purposes :-(

if you have an answer then i'll post this as another question.

What you can do is edit the modems S-Registers to pick up after x amount of rings.  In my modems manual it lists S0 as the proper register.  So to put ATs0=x in your modems NVram, type ATs0=x&w&w1.  This is a pretty common register, so chances are yours is the same.  

Good luck
