I have configured WCCPv2 between WSA S160 ( 6.3.1-025) and ASA5540 (8.2(1)109).
Everything seems to be OK by "show wccp *" on ASA and showing wccp debugging messages (level 4) on S160. Despite of it, WCCP redirection does not work.
If I use packet-capture I figure out that S160 receives GRE packets with TCP SYN from particular LAN host to WWW sites but S160 does not handle them and does not send anything back to ASA.
It is an Exempt from authentication for this LAN host and in Forward proxy mode everything works well.
I have attached an example of a packet-capture (S160.txt - renamed from .cap) and debugging messages from S160 & "show" from ASA.
Does anybody have any idea what the problem is and how I can resolve it ?
