We are going into a WAAS deployment and have PIX firewalls running 6.3 code. We are looking to place the WAAS devices on the inside of our firewalls at each end. They will be deployed with WCCP, not inline mode.
I know the "inspect" commands are available in 7.x code, but it will be a big pain to upgrade these firewalls.
From what I read, the WAAS devices use IP or TCP options. Is this true? That's why you need the inspect on 7.x? Is there a way to preserve the options in 6.3 code?
Thanks in advance for a reply! : )
