[c-nsp] IP Tunneling Question

[Charles Wyble]

All,


I'm looking to setup a VPN with a couple colocation providers who are 
friends of mine, and have some under utilized address space. They are 
supporting some security research I am doing (a darknet/honeynet). [1]

I am exploring different options to utilize that IP space on my lab 
servers.

How do folks typically accomplish IP tunneling? IPSEC tunnels? Do you 
use GRE? What about OpenVPN?

I can easily setup any of the above mentioned approaches as howtos 
abound. Just wondering if there is anything to consider for this 
scenario to reduce overhead and packet molestation as much as possible.

Thanks.

visualization tools and methodologies etc.
