Hi all, hoping get some help here this is my question.

I'm trying to create a small network. What I have now is an ADSL connection and 128 Kbits dedicated connection (router provided by telecom company)

I want to connect both internet providers to a single computer, enable this computer with routing to choose the internet connection to use depending the case, install a firewall. Also in this computer I would like to have an internet web server for clients or whathever.

I just need some guide. I would like to keep the software solution of this computer as Windows. Can you give advise about products ?
Can I use ISA server for all I want ?
Any other ?
Mixed products ?
Just a guide or urls to help me. Thanks.

Diego
