See my thoughts on the Imail forum on 587.   John Tolmachoff Engineer/Consultant/Owner eServices For You   -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Matt Sent: Friday, February 25, 2005 4:50 PM To: Declude.JunkMail@declude.com Subject: Re: [Declude.JunkMail] Spammed on port 2525   Here's what I am using for a mail server located at 192.168.1.1 for this example.  IMail is configured to listen on port 587, but to the outside world it appears as both port 25 and 587.  Even though one would think that you didn't have to NAT 587 to 587, in this case you do because of the other rules for that IP (or so I was told).  I assume that you are configured differently and that does matter, so you might want to share that before making the edits yourself.  ip nat inside source static tcp 192.168.1.1 25 192.168.1.1 25 extendable no-alias ip nat inside source static tcp 192.168.1.1 587 192.168.1.1 25 extendable no-alias ip nat inside source static tcp 192.168.1.1 587 192.168.1.1 587 extendable no-alias I assume that you know how to config term your router.  If not, it won't be straight forward without a crib sheet or experienced help to guide you through it rather than risk messing it up.

I was just checking my logs and I've been receiving spam on port 2525   Can anyone share the necessary Cisco IOS commands to let the Cisco router do port translation? P.S. IOS isn't my primary language... -- ===================================================== MailPure custom filters for Declude JunkMail Pro. http://www.mailpure.com/software/ =====================================================
