SBS2003+cisco801

I am using Server 2003 and I need to make a dial-in server for remote access
and that for only 1 user. I have 2 NICs WAN-86.35.72.29 gatew 86.35.72.17 and
LAN
192.168.16.2.
I ahve another 10 users on the domain and I want to make dial-in server. I
have the isdn and the isdn router Cisco 801 that is using 192.168.16.5.
I am using Pc Anywhere as Host so that the dial-in user can have access to
some database.
My problem is : do I need to make some adjustment inside SBS like additional
routing or run the remote access wizard for vpn? or anything else?

Thank you very much
