Насчёт "vtun безопаснее" - надо читать
http://www.cs.auckland.ac.nz/%7Epgut001/pubs/linux_vpn.txt и дрожать (2
раза). Как справедливо заметил автор, использование шифрования самого по
себе ничуть не гарантирует безопасности.
После прочтения не возникает желания использовать ничего, кроме OpenVPN
(http://openvpn.sourceforge.net/) или KAME's IPsec utilities
(http://ipsec-tools.sourceforge.net/).
Я, конечно, не эксперт по криптоустойчивости, но лучше уж перебдеть, чем
недобдеть. В этом плане имеющийся в Sisyphus ipsec_tunnel немного
подмочен в http://www.linux-magazine.com/issue/39/VPN_Insecurity.pdf,
"there’s ... something like ipsec_tunnel
http://ringstrom.mine.nu/ipsec_tunnel/ to retrofit to older ones.
ipsec_tunnel is an extremely lightweight (38K of source code) IPsec ESP
implementation, although it appears to be missing some functionality
such as the sliding-window replay protection that would have to be added
to provide proper security."
