(1) ssh tunnels, in particular tunneling PPP over ssh
 (+) easy to setup
 (-) only works linux-linux
 (-) tunnels everything over tcp.

this is not right  FSecure is for Window$ Client/Server
there is also a free version.... OpenSSH for Window$

Betreff: Re: any VPN program at linux?

I would like to use VPN at linux?
Do you know any recommendable program?

short answer: plenty... 

(1) ssh tunnels, in particular tunneling PPP over ssh
  (+) easy to setup
  (-) only works linux-linux
  (-) tunnels everything over tcp.

(2) CIPE
  (+) comes with redhat.
  (+) a bit better performances (UDP, not TCP like ssh)
  (o) harder to setup then ssh, but not as hard as IPSEC ;-)
  (-) no Windows support I know off.

(3) FreeSwan (IPSEC)
  (+) full IPSec implementation. Very interoperaple.
  (+) very flexible
  (-) pain to setup
  (-) problems with NAT

(4) PPTP (Microsoft VPN)
  (+) works great with all versions of Windows.
  (+) not hard to setup.
  (-) frequently considered less secure then alternatives.
  (-) not as flexible and not as good interoperable as IPSec.
      (but works great as long as you deal with Windows/Linux machines)

There is a pretty good New Riders book: Building Linux VPNs. It walks
you through all these systems (and probably a couple more I forgot)
