i am currently using a cable modem and provider is comcast.  i have a broadband cisco router that allows vpn ipsec & pptp.  i dont want to use that as vpn, i want to use ISA.  

i currently have the network behind the router. i have a certificate server and ISA server setup.  i cant access the ISA server from workstation from home cable internet connection.

does the ISA server need to be in front of the router?

1.  ISA is hard to setup.  If you haven't deal with ISA before and would like to have it setup in a jiffy, then you might want to reconsider using the router.

2.  Dos ISA need to be in front of the router?  NO.  Does it need to be in front of the FIREWALL?  Maybe (or yes).  ISA is a firewall.  The main purpose of the firewall is to filter/block traffic.  If your router is also acting as a firewall, then there's not a whole lot for ISA to filter in the first place, but it might work.  Just keep in mind that anytime you want to open up a service, you'll need to make sure that the ports is open for BOTH firewall (if you have another one in front, that is).

3.  You'll need to open up the port so you can access the ISA server.  Depending on how you'd like to access it.  By default, nobody from the outside can manage the server unless you open up the ports and rules neccessary for you to do so.  

4.  Does ISA do VPN?  Since you were talking about VPN, I thought you'd need both ISA and "Routing and Remote Access" turned on to accomplish that task.
