I do not know if you guys received my original message so I will repeat.

IPsec is part of IPv6 security enchantment which is back ported to IPv4. 
OpenVPN is open source project released
under GPL license which is not fully compliant VPN protocol (not 
compliant with IPsec) but easy to configure. Unless all of your client 
machines use OpenVPN you will be in big troubles.

Cisco VPN is a joke and there is published algorithm how to brake into 
it. If you do not believe me follow the link


All above being said Cisco 3000 is very popular and it looks good in the 
eyes of management.

I am not an expert in Internet security but it seems to me that IPsec is 
way to go if you are serious about VPN.


P. S. Make no mistake. OpenVPN has nothing to do with OpenBSD project. 
As a matter of fact OpenBSD
guys highly favor IPsec over OpenVPN.
