Can P2 be used with transparent WCCP redirection?

[parleysmith]

I have the following scenario for a WSA:

A. P1 is configured as the internal facing proxy interface.

B. P2 is configured as the public facing interface on a separate subnet from P1.

C. IP spoofing has been enabled.

D. The WSA uses transparent redirection based on the destination port with WCCP service 91 and WCCP service 92 with source port redirection for the return path.

F. IP spoofing is then disabled.

After IP spoofing is disabled, will transparently proxied traffic only use the P1 interface? Will the second (return path) WCCP service need to be disabled on the WSA?

I'm interested in being able to use both P1 and P2 to reduce proxied traffic congestion on the P1 interface after IP spoofing is disabled.

Hi Parleysmith,

WCCP will only be used to redirect client traffic on the P1 once it is disabled on the P2 interface using service ID 92. The service ID 92 also needs to be disable on the WSA.
