[isp-caching] Alteon 180 L4 Switch and CacheFlow CA-645 help

["Shawn Xu" <shawn@...>]

I have configured our Alteon 180 L4 switch to redirect http traffic to CA-
645 cache box which is supposedly configured as transparent mode.

In fact, I don't know how to configure CA-645 as transparent mode, and 
how to check it is working as transparent mode? On the cache box, using 
web interface to get management, network, then services, from there, if I 
configured Explicit mode, then the client can go to the Internet, but 
there is nothing showing in http://x.x.x.x:8081/Accesslog/tail~10. If I 
chose Transparent mode, you can see something in the Accesslog like

2004-04-05 19:29:04 66.199.158.229 - Security-Gateway-HTTP-Service 
CacheFlow-645 206.47.74.31 
GET /RealMedia/ads/adstream_jx.ads/www.toronto.com/toron/home@x27 - 503 
2924 370 49883 HTTP/1.1 oas.toronto.com Mozilla/4.0+
(compatible;+MSIE+6.0;+Windows+NT+5.0)

but the client cannot search the Internet. It says web site was found, 
then waiting for reply, and finally tcp_error from IE. In this case, the 
other stuff, like ping, traceroute, netmeeting,etc,non-http traffic 
working as normal. Because I configured L4 switch to redirect only http 
traffic to the cache box, while the  cache box is not working properly.

For the testing, I don't use filter, policy, or security, nothing else, 
just want to make basic transparent cache working.

Whoever has CacheFlow experience, please help with how to configure the 
Cacheflow to work as transparent mode. It means working if I see the log 
like above.

Your help will highly appreciated.
