WAAS 4.0.9 /WAE 612-K9 not accelerating

Question

I have a central site and four remote sites connected via leased lines, I receive a demo with 3 WAE-612-K9 (4.0.9 s/w version)for testing purposes. I connect one WAE as a CM and one WAE as application acceleration at the central site and the another at the remote site. I want to have Web and MS Exchange acceleration at first but I don't see any improvement. The central site have one 3845 router and the remote 2811 both with IOS 12.4(13c) version. Any help please ?

Answer 1

Yes I see some connetions to be optmized, my problem/question is why I cannot see http optimization for my intranet site since the traffic is marked PT .
I am using the default policy in both WAEs , as I can see the policy marks http traffic to be full optimized.
On the cms I cannot see any Reduction taking place , all traffic marks as 0.
In both WAEs sh statistics dre shows all 0's
and no hard drive space used.
The mail servers are MS Exchange 2003 with smtp connectors between them , one server per site. It's possible to improve e-mail too ?
