Setting up VPN

We have a single-location network of about 25 machines
(mixed 2K and XP), with a single domain controller running
Win2K Server. The server acts as PDC and DNS server, with
DHCP being done by a Cisco 675 which controls internet
access (DSL). All IP addresses are private, with the
Cisco using 10.0.0.1. We want to set up a VPN to allow
remote access so some employees can work from home or
other remote sites.

My questions are:

Will we need a public IP address, for either the internet
router or the network card in the server connecting to the
internet?

Will we need a different modem or router other than the
Cisco?

Should we install a hardware firewall? (We currently run
a software firewall.)

Any help would be greatly appreciated. Thanks

Cisco 675:Yes it needs a public IP and your ISP assigns it. You might want
to consider getting a static IP from your ISP to make things easier or
alternatively you can use DDNS providers like www.no-ip.com www.zoneedit.com
to map a dynamic IP to a FQDN.
Server: No you will not need a public IP. Setup port forwarding on your
internet router to forward
PPTP: 1723 IP 47 Established (GRE) some call it PPTP- Pass through
L2TP: UDP:500 ...

What kind of software firewall are you running?
 
We are currently running Zone Alarm.
