Yes, thats right, or at least how I understand it. Well, maybe one small
correction in my scenario. The LAN1 in the small example below is the
interface towards the internet.
The router sets up a gre tunnel and udp port 2048 will be used to
communicate to towards the webcache

Dear Roger,
Thank you for detail explaination. what i am understand from your writeup
that IN or OUT is for direction of traffic. Like you said "you want all
users from LAN2 and LAN3 to communicate with the cache, just configure the
OUT parameter on the interface towards LAN1" it means traffic is going out
of LAN1 so we will use OUT regardless of where WCCP Server is located.
Please correct me, if i got wrong...
Regards

Hi,
AFAIK (and if I understood the VoD from ipexpert right), it doesnt matter
whether you configure IN or OUT but you cannot do both and it depends on the
topology. Take a look at the following:
LAN1
|
<router>
| |
LAN2 LAN3
So if your web cache is located on LAN1, and you want all users from LAN2
and LAN3 to communicate with the cache, just configure the OUT parameter on
the interface towards LAN1.
If you only want clients from LAN2 to talk to the cache, just configure the
IN option on LAN2.
There is also a possibility to limit the access to the cache via ACL's. The
communication itself from the router to the cache is "kind of automatic",
most of the stuff will be initiated via the cache.
So hopefully I got that right, otherwise folks out there on the list will
correct it :o))
regards
Roger

Betreff: wccp redirection
Hi experts,
I have some confusion about wccp redirection. If i configure like :
inter fa 0/0
ip wccp web-cache redirect *in
*what is the meaning of "in". I am confuse about whether it direction of web
traffic mean wccp for packet that is coming IN or its means wccp system is
inside of this interface?
Please clearify it
