PIX 501 website traffic out and come back in open original image

I am using a CISCO PIX 501 with port 80 forwarded to my web server. I am using a flash content manager called fCMS on my website. The way the content manager is pathed it has to go out to

the web and come back into the web server. The PIX does not allow this but I don't know why. Does anybody know how to allow traffic to go out and come back in? Thank you for your help in advance!



You can't do that on a PIX 501.

However, what you -can- do is reconfigure you DNS services so that when an inside host makes a request to

it is told the internal IP address rather than the external IP address.

The mechanisms for configuring that depend upon whether your DNS server is inside or outside. If it is outside, it would be configured by using the 'dns' keyword on a 'static' command, if you are using PIX 6.3; in PIX 6.2, you would look at the 'alias' command instead.

Is "

Sorry for the late reply! When an inside host goes to

it resolves to the internal IP which is why we are so confused as to why this is a problem. The fCMS software support can't figure it out either! Thanks!

is an internal hosted server. Thanks!

The Pix won't allow traffic to exit the same interface that it entered from. You would have to resolve the host locally so that it used the internal address and not the external.
