WCCP IP Spoofing

[rlourenco]

Hello,

from the documentation available I could see that we may use the IP spoofing feature for HTTP traffic.

Is it possible to use this feature for FTP?

What I mean is: is there a away to transparently (WCCP srvc 60) cache FTP traffic and keep the client IP address in the sessions between the Content Engine and the FTP server.

Thanks in advance.

I think it might be possible for using Ip spoofing feature for Ftp traffic also with the HTTP traffic.Check with below link for more information.

Cisco Application and Content Networking System (ACNS) Software Version 4.2 Enterprise Edition is the latest release for caching and content delivery. Running on the Cisco Content Engine (Cisco CE 7320 and CE 500 Series), Cisco Content Distribution Manager (Cisco CDM 4650 and CDM 4630), and Cisco Content Router (Cisco CR 4430) platforms, Cisco ACNS Software 4.2 features:

Web content preloading for Hypertext Transfer Protocol (HTTP), File Transfer Protocol (FTP), and Microsoft Windows Media (MMS) objects

I don´t think it is. See below a response from Cisco related to that topic:

3.) If source spoofing is enabled for one WCCP Service, will it affect all WCCP services? There's just a global command to enable the spoofing (wccp spoof-client-ip enable). Customer wants spoofing for HTTP to avoid upstream auth issues but does not want to do it for the high video streaming bit rates.

ANSWER -- No. HTTP cache app service is the only one that supports IP spoofing currently. This is confusing since the command to enable spoofing appears to be a "global" command, "wccp spoof-client-ip enable." xxx has asked development to change the syntax to to "wccp web-cache spoof-client-ip enable," but there has been no commitment.

and btw. the latest ACNS release is 5.2, not 4.2.

Hello,

Thanks for your replies.

I also checked with Cisco and obtained the same answer as you. WCCP IP spofing feature is, for now, only available for HTTP traffic.
