Thanks Kai. I have few more things I think you have answers for..

1. 2501 box does not have async port but can can configure aync1
   (virtually)

2. Modem is to be connected to Aux port. Any idea on the cable.. can I
   use console cable..

3. My provider (who answers) have Livingston TS. Will it respond if I use
   DDR through my cisco 2501 ?

   Then, ip route 0.0.0.0 0.0.0.0 async1 (does this suffice)

4. Can I configure my async1 without assiging ip to it. My provider is to
   allocate ip dynamically..

--thanks,
