No, if you have a policy enabled (or if you are even using IPSec VPN connections) you will be generating data... There's a bit to the MMC, but it is pretty cool... I think the refresh rate defaults to 45 seconds, but you can change that.

If you right click on the machine (in this case, the ISA box displayed there) and go to Statistics, you'll see detailed counters that may let you know where your problem exists. You can also expand out your main/quick mode elements, and get the properties of those guys for a reference to how you've got it configured.

The constant "Negotiating" should be generating errors- hopefully those errors will allow you to figure it out. You can also turn on auditing/logging of IPSec connections, which will place events in the log...

First time using this monitor, does the Negotiating have to stop in order to get results? My ping never stops "Negotiating IP Security".

Has anyone loaded the IPSec Monitor MMC to see what is going on there?
Might be valuable...

Ah, you are stuck at the same point I am. Phase 2 never completes.

I have been unable to devote the time needed to find this.

http://www.ISAserver.org

I am setting up the IPSec Tunnel VPN with ISA 2k4 and Sonicwall. I have
the oddest
things happening with this. I see the tunnel establish on the sonicwall
and can see my
network listed as one of the established networks on the Sonicwall Device.
When I try
a ping from my ISA server I get a string of "Negotiating IP Security" for
my result.
When I ping from the Sonicwall side I get a no reply.

I look inside of the logs of the Sonicwall logs and see the tunnel
establishing there as
well, but, immediately afterwards I see "IKE Responder: IPSec proposal
does not
match (Phase 2) IKE Responder: ESP Perfect Forward Secrecy mismatch". I
removed
Perfect forward secrecy to eliminate that and only received "IKE
Responder: IPSec
proposal does not match (Phase 2)"

For ISA I have 3DES and SHA1 as my Encryption and Integrity Algorithms,
Generate a
new key every 3600 seconds. On the Sonicwall I have my Phase 2
Encryption/Authentication set to "Strong Encrypt and Authenticate (ESP
3DES HMAC
SHA1)".

I have tried changing the Phase 2 information just to see if I generate a
different
error. I get the same error but the tunnel doesn't establish when I do
that.

At this point it feels like so close but yet so far. Any ideas on what
else I can try?
