RE: VPN server

Our current topology is frame relay, cisco routers, T1 from central office
to the frame cloud, branch offices use expensive and slow 64kb/128kb
connections to the cloud.

Any thoughts on replacing the cloud with router to router vpn over the
internet ?

Esp where less expensive, higher speed DSL is used to connect the remote
branches to the internet.

Is DSL too unreliable for business use ?

Thanks,

Steve Richter

The Linksys Router is an interesting animal, because it allows router to
router level VPN.  So anything behind the router on one side can access
anything behind the router on the other side without any client
software.  The default route points to the router and the router does
the rest.  Very slick.  We are considering deploying this as a back up
solution to one of our clients who currently uses ISDN to back up their
Frame Relay network.

VPN is either a client to network or network to network, encrypted
TCP/IP connection.  It requires some client software that connects to an
authenticating server.

A solid VPN server is the iSeries.

The documentation in the Information Center does a pretty good job in
describing the setup, if you can find it.  Try

http://publib.boulder.ibm.com/pubs/html/as400/v5r1/ic2924/info/rzaja/rza
javpnprotocols.htm

Or you could look at something like the Linksys VPN/Router for about
$180.

Either way, the VPN authentication server needs to be accessable from
the Internet.

The O'Reilly is an resource!

Where's a good source for information on VPN servers vs clients? The
concept is easy to understand; the implementation appears to be
spreading out from software-only to VPN appliances, and it's not clear
to me what's required on either end.  I'm looking for the simplest,
least expensive solution, naturally.  I want to provide a customer
access to my AS/400 via the internet using VPN.

1. Is there a standard VPN protocol?  I.e. there appears to be IPsec, M$

PPTP, and probably others.  Am I correct in assuming these are
incompatible?

2. Are these VPN appliances servers, or clients?

3. What's a ballpark cost to provide VPN for 3-5 users?
