Transparent Proxying With PIX

[andyhsu]

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!

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.
