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 ?
