VPN Solutions for Small/Medium Businesses?
artbeall asks: "I work for a small company and we are looking at various commercial VPN solutions, however many seem to be too expensive for us. I am interested in what solutions other small/medium size companies are using for their VPN. Of course, we want a SECURE system that is compatible with common network gear like Cisco as well as being able to run the VPN client on Linux, Solaris, and Windows. Does anyone have suggestions or ideas?"
Why not use openvpn ? We run this on Linux, Openbsd and Windows.
At work (~90 employees...I guess that would qualify as medium-sized??) we use a Cisco VPN 3000 Concentrator. It's been rock-solid for us for two years now, and I'd highly recommend it. If you want to go the VPN-client route, cisco has official clients for Mac, Windows and Linux, but the box is also compatible with the PPTP vpn clients that come with most modern operating systems and it's also fully IPsec compatible. So...for example, if you wanted to, you could set up a linux gateway at home that would connect to your work VPN and establish a LANLAN VPN link.
If this proves to be too expensive, you ought to look ag OpenVPN. It's quite stable at this point, and they have clients for Windows, Mac and Linux as well. You'll have to have some amount of knowledge of linux networking/firewalling to get it set up right, but there's plenty of documentation out there to guide you.
Yeah, either that, or you could tell your boss you need a Pix, buy the same thing, with the same innards, by the same company, and buy yourself a nice 24" LCD with the leftover $700.
30 concurrant VPN connections. Dual internet ports that can function as failover or load balancing. Built in 4-pt switch. $180. That's small business.

Go to openvpn.net. It's very straightforward to get a multiuser openvpn server up, using pre-shared keys or certificates. It's free, it's simple, it's multiplatform, and it's sufficiently secure for business purposes.
(However, if by "compatible with common network gear" you mean you need to host a VPN endpoint on a Cisco box, then OpenVPN probably won't work. If you can pass the connection through a firewall to a DMZ server, though, it should work fine.)
If you want a completely free solution, use OpenVPN hosted on an OpenBSD (or other free OS) firewall.

That site has a very easy to understand howto with plenty of client and server examples. After a day of trawling through the OpenVPN documents, this howto was a breath of fresh air.
I have used IPCop for many, many months. With
the OpenVPN addon, it makes a sweet RoadWarrior
setup. The OpenVPN GUI is even easy enough for
our executives to use.
For us and our 30-something employees, it cost
us nothing to put IPCop online. It ran for a
year on a P-III/700mHz/256M Dell. We recently
upgraded the RAM to 768M so we could make better
use of the Squid cache.
You can get an IPCop server online with VPN in
under an hour. As long as you have a computer
in the spare parts closet, IPCop is far less
expensive than any other solution.
