In our dev CSS routed mode we have 2 web servers in the DMZ that are trying to connect to our inside mail servers thru SMTP. It initiates a 3way handshake but the message body "helo" never gets to the mail server. After several traces we noticed that the message body never leaves the CSS. Is there anything in the CSS that may prevent the packets from getting to its destination? I can ping and open a connection with SMTP but that's it...Any Ideas?
