Hello,

        I guess it all depends on what you need, lets say for example you have
two offices. 

One in location A with static IP A.A.A.A and one in location B with
static IP B.B.B.B. 

Why go out and spend all kinds of money on VPN's --- they all do mostly
the same thing ... they usually all support the same encryption levels.

Why not use FreeS/Wan or SuperFreeS/Wan ? You take two average boxes and
install linux, base install nothing more. Really all you need is a
running kernel, you could easily use a bootable CD. 

Anyways base install and build Super FreeS/wan ... on VPN box at
location A we allow only UDP port 500 traffic and IP protocol 50 from IP
B.B.B.B only .. all other traffic is dropped. We do the same on box B at
location B, allowing only UDP port 500 and IP protocol 50 from IP
A.A.A.A.

You use then only allow AES-256 with SHA-1-256 bit encryption using RSA
keys.

Once configured their is NO maintenance at all required. I am using a
similar solution and since the initial install I never have had to
touch the boxes.

All this cost me about $1500 because I had to buy two boxes at $700 a
piece.

Good afternoon list,

Yet again, it's time for me to pick your brain...  I've been asked to
develop a VPN solution that will require little to no maintenance.

Project Goal: Connect two computers, on two public networks, to secure
data transfers between the two.  Ex: Offsite backup.

If anyone can recommend any hardware solutions that would establish a
secure connection...  I was looking into Cisco 1712 series...

The sky is the limit on this one, and I've been given a fairly
reasonable budget...

I've never setup anything like this before, so I'm open to any, and
all suggestions...

Thank you,
Nick Diotte
