I've installed a PIX 515e. We have an Exim mail relay that sits infront of the PIX. The mail relay was connecting to our Exchange 5.5 servers before the PIX installation through a router only but now they are sitting behind the PIX. How can I get this traffic to pass through the PIX and reach the mail servers? I don't know how to do it using a static xlate because there is one IP for the mail relay but five mail servers behind the PIX each with its own IP.
