Can ICS work with a dial-up modem? (W2K)

[kef999]

Can Internet Connection Sharing (ICS), the facility automatically built into Windows for enabling client computers on a LAN to use the Internet interface on a gateway/host computer, actually work with a dial-up modem? I've been trying with my own recently-devised setup but can't get it working.

I've tried with both auto assignment of IP addresses and with manual addresses but neither seem to work.

What happens is that the client machine attempts to dial up the ISP via the gateway machine but then times out well before the gateway can establish the connection.

Do I presume correctly that the only way that you can get manual (static) addressing to work is by getting your ISP to assign you a permanent IP address?

All the LAN adaptors' advertising and ICS guides published on the Internet suggest that ICS works with all sorts of modems, including dial-up modems, but I'm beginning to think that that's wrong and that ICS assumes a permanently-connected modem, such as cable or DSL.

Anyone with some REAL experience of this who can help?

* Disable all firewalls on all machines until the problem is resolved.

Uncheck the ics option on the wtk machine that has the modem installed and is also hosting the ics connection. Next go to the Lan adapter settings and change the tcpip settings to obtain automatically. Reboot the machine. Go back to the dialup settings and re-add the checkmark to the ics option. reboot the machine. Dialup to the net to establish a connection.

Go to the other computers on the Lan and change the tcpip settings to obtain automatically. reboot all machines. (if any of the client machines has their own dialup connection created, go to Internet options/connections tab and make sure it's set to never dial a connection.

result = the wtk machine will obtain a dynamic ip from the isp. wtk will also auto assign an ip and gateway ip to the Lan settings tcpip stack. Furthermore, each client machine upon boot will auto receive an assigned ip from wtk. Test by browsing the net from a client machine.

POBrien,

I performed your instructions to the letter but with no success. Again, the client machine times out well before the gateway establishes the connection with the ISP.

Sure, you can achieve a working system if you first of all dial up and make the connection from the gateway machine and then go to the client and initiate the browser or the e-mail program from there, but that isn't true Internet Connection Sharing, is it? With ICS, you're supposed to get on to the Internet directly from any client machine.

The mere fact that no icon relating to the Internet connection appears on the screen of the client suggests to me that ICS assumes an always-on connection at the gateway machine. That would therefore exclude all dial-up modems from using ICS. The fact that webpages can be routed through to the client once the gateway has established the connection, ie if I initiate the browser or e-mail program a second time from the client, is again an indication of that.

If someone knows different, then PLEASE let me know!!!

Thank you for your summation. Something else must be misconfigured on the ics machine or Lan setup that is preventing ics from working correctly.

good luck,
