Hey all,

Can anyone offer a comparison between L2TP, EoIP, IPIP, and GRE over IPSec in terms of CPU usage and bandwidth usage overhead? Since they are all using IPSec we can just ignore that since the IPSec overhead will be the same no matter what it is encrypting. But how about the different tunnels? Right now I am using EoIP over IPSec and was thinking about switching to something with a bit less overhead. Thanks.

Still no answer/findings? I am also interested in.
