Hello

You can
- define a new service HTTP_PROXY_REDIRECT type other, IP Protocol: 6,
advanced,  match: SRV_REDIRECT(80,proxy_IP,proxy_port)
- create a rule: clients to any service HTTP_PROXY_REDIRECT accept

Objet :     [FW-1] Using HTTP Proxies


Good day to all.

I was looking into Firewall-1 as I am in need of configuring it to use
an external HTTP Proxy. Here is my topology:

1) FW1 NG with several HTTP rules
2) Clients are NOT configured to use FW1 as proxy (as matter of fact
they are not configured to use anyone as proxy)

I need to "redirect" all traffic, sent out via HTTP, through FW1 to a
proxy server. I've seen that this is possible using the option HTTP Next
Proxy. However, the following questions came to mind:

1) Is it possible to put this Proxy server in my DMZ? (traffic will have
to go back through FW1 without creating a loop)
2) Is there any other way (other than HTTP Next Proxy) that might allow
me to configure the proxy server in the individual rules without using
CVP or UFP? I need to mantain a few other rules letting HTTP out without
passing through the proxy.

Thank you very much for any help.

Bernardo.
