VPN (off-topic)

[zottmann]

Hi !! 

Sorry for this off-topic, but I guess this should be a good place to ask for 
advice ... 

We use iptables, and we are needing to install a vpn solution in order to 
build vpns with other companies that may be using various vpn solutions, so 
we need one that can build vpns based on standards, like ipsec. 

I have heard about OpenVPN and FreeSwan. 

Are these good solutions? Do they have any management resources, like 
graphical interfaces for setting up vpns and getting information about its 
use? 

Are there any other open source or free implementation of vpn that is better 
suited for use with iptables? 

Thanks in Advance,
