EtherIP-IPSec tunnel throughput on NET4501

[Tarquin Joseph <tarquin_(_dot_)_joseph_(_at_)_gmail_(_dot_)_com>]

Hi,

I'm using three NET4501's in a full mesh EtherIP-IPSec tunnel.  Yes I
know it may not be the best way but it's useful for a particular
application where I want to do site to site connectivity over an IP
network without needing to know the details of the internal addressing
scheme.

I was wondering if any one has done an EtherIP-IPSec tunnel using the
NET4501's (without acceleration card) and if so what throughput were
you able to get out of it (you may not have done three like I have,
maybe just two).

Currently the maximum I can push is about 2.5Mbps using AES-MD5 in
main and quick modes with no PFS.

If this is the wrong list for this topic, please accept my apologies.

Regards,

Tarquin.
