PIX 501 - Having trouble with SMTP/POP3

PIX 501 - Having trouble with SMTP/POP3

PIX 501 - Having trouble with SMTP/POP3

Decided to upgrade my Linksys FW with a PIX 501.

SMTP/POP3,FTP and HTTP work flawlessly through the Linksys.
Because of this, I'm sure I don't have a POP3 client or server issue.

When I switch to the PIX, I can get HTTP and FTP to work, but not mail. Any direction would be appreciated.

RE: PIX 501 - Having trouble with SMTP/POP3

You are missing a nat (inside) 1... statement. If your mail server is exchange you also need to disable the fixup protocol smtp.

Thank-you, it now works.
