VPN software

[alexei kozlov]

Hello, list.
Just learning the FreeBSD and have one question:

currently I am behind the firewall, and to go to  internet I (my ISP) 
setup VPN in windowsxp.

On one of my low profile machine (450MHz, K6-II) I set up FreeBSD.  I 
setup ethernet adapter and can connect to other machines. But I can not 
go out to internet . I new that I need setup vpn in FBSD, but I do not 
know which one, since I found at least three vpn programs. Which program 
do you use ?

Regards,
Alexei
