I got a 515E with Pix os 7.0. This Pix work as a border firewall between my border router and my internal network.
Some of my customers inside require a SMTP over SSL connection to the outside SMTP server. I opened up all necessary ports on the pix but still in vain. Finally I tried getting one of the customer internal network to be able to access ALL ports on the outside. By right when I did that, that particular client should be able to access all services on the Internet. But the same error came out with the SMTPoverSSL issue. Im sure its the PIX's problem because I had tried getting the PIX out and connect directly to the router, it works!
Anyone experts out there who can advise me? Thanks in advance.
