[Openswan Users] What are Performance notes in OpenSwan?

Hello All

I am attempting to use OpenSwan VPN gateways to my following attached
network topology design, there are 3 levels of LAN in this network.

The Algorithms are AES-128 with SHA1-160 and RSA Authentication in tunnel

In first step I used GRE + IPSec together, so there were reduced tunnel
numbers with a lot of routes (either static or dynamic).

Then I create Full mesh (site to site) configuration (any host in any subnet
can ping other in ESP mode) that provide (705*704)/2 tunnels, awful!!! The
tunnel management in last case will be very difficult.

   - I would like to know what solution (IPSec with GRE, Full Mesh, OE with
   DNSSEC) is the best choice for high performance and reliable secure network?
   - I would like to know what hardware (CPU + Main Memory + Storage) are
   required to saturate this network topology without any failures?

Any help would be great.
