I am having issues recieving mail on the internal network when sent from machines in my dmz. I can get mail to yahoo or any external mail system when sending from the dmz machines, but I cannot get the mail on the internal network? I am using live IP's in my dmz, could that be it?
access-list 110 permit tcp any host 220.127.116.11 eq smtp
Half of my live ip's are used on the external int and the other half used in the dmz. The static mapping for my mail server is using a live IP on the external int. Can I even do this? Did I forget to add a route?
