Transparent Proxying With PIX

Hello,

We recently migrated from an OpenBSD/PacketFilter firewall solution to a Pix 515E (6.2). In our previous setup, we used the firewall to redirect all port 80 requests to the proxy server in order to operate the proxy transparently. I have yet to figure out how to duplicate this on the Pix. The setup we use is as follows:

|Client|

|(172.16.10.100/24)

|

|(172.16.10.1/24)

|PIX 515E|---------------------|INTERNET|

|(172.16.20.1/24)

|

|(172.16.20.100/24)

|Squid Proxy|

Any ideas on how we can recreate our transparent proxy on the Pix would be appreciated. Thanks in advance!

Re: Transparent Proxying With PIX

Hi,

Unfortunatelly there is no way for that kind of redirection on the PIX. Instead if you have a Cisco router, try to use the WCCP protocol. Strictly speaking Cisco gives a solution for transp. proxying with a Cisco router and a Content Engine (cache engine) using that WCCP protocol.

Thanks for the response; that's kind of what I figured after doing additional research on the net.
