SEP-E and NAT-T

[gdelpanta]

I have installed a VPN 3020 with one SEP-E, when i enable NAT-T, SEP Statistcs show that all session are encrypted in software; conversely when i disable NAT-T and Session use UDP encapsulation (default 10000), SEP Statistics show that SEP-E is working ?

Is it possible ?

please excuse me for misunderstanding.

sep-e module performs data encryption functions in hardware, regardless whether nat-t is enabled or not.

... as i supposed when i have enabled NAT-T on VPN 3020 during installation.

But unfortunatly when i have:

- IPSec/UDP 3DES-168 Sessions --> SEP-E Works

and when i have

- IPSec/NAT-T 3DES-168 Sessions --> SEP-E Doesn't Works

The evidence of this by looking:

Monitoring | Sessions | SEPs

i can post further or deepen information if you want

but the behaviour of 3020 described above reflect what is happening.

A bug ??

I'm using vpn3000-4.7.2.C-k9.bin Software.
