I have a dial-up modem connected to my router's AUX port.
Using this setup, I need to get remote users to access our internal servers via dial-up.
The users aren't network admins, so they should not have exec access to the routers. They only need to be able to access the servers on our system, i.e. I need to route their Laptops's traffic via the aux port to the intended server.
Is there a way of configuring the router and modem to do this? Or do I need more equipment in order for this to work?
The router is a 2960 series and the modem is a US Robotics dial up modem.
Any help is greatly appreciated. Thanks!

For diarect dial connection, there should not be a lot of difference - the AUX port should run PPP automatically and as long as the PC recognises this it should negotiate and connect.

Yes, configure ppp for the aux and dial-in. Performances won;t be stellar, but it works.

Hi, thanks for the tip, but I thought you can't configure ppp on AUX ports?

These configs are a bit old and crusty , but they should give you an idea on how to set up async routing on the AUX ports. As Paolo says , performance is not brilliant, but it will work ... The chat scripts would likely need to be modified to suit your particular modems -

Hi, Thanks for the tip. If I were dialing from a Laptop connected to a modem, would there be any differences in the configuration?
Thanks.

Thanks for the tip, guys. I've finally been able to get this run-down modem to work.
