Re: VPNs

["Davis, Thomas R." <tdavis () INDIANA EDU>]

Hi Leslie,
  Each of our two large campuses (Indianapolis and Bloomington) has two
Cisco VPN 3030 systems, each capable of handling 1500 simultaneous
tunnels.  On each campus, one is used to secure wireless and allow
remote access.  The second is a special purpose server that only a
select few have access to (it gives out a limited range of IP addresses
that are closely monitored).  These VPN servers authenticate to a
Windows 2000-based RADIUS server, which in turn talks to our Windows
2000 ADS domain controllers.

  All of our "authorized" wireless access points are VLAN-ed
into/through a VPN server to provide authenticated and encrypted
wireless communications.  And, we've been very happy with these
products.

Hope this helps,

Columbia is investigating means for implementing and supporting a VPN
for the university.  The demand is clear, but a solution that will scale

and be supportable is not so clear.

I would like to know if you have implemented a VPN for your university,
what products are being used, and how it is working.  I'm interested in
both successes and disappointments.

Thanks in advance for your responses.
