Thanks to everyone in advance. I am stuck in the middle of a project where there was an existing Cisco 1720 that looks like it had grown out of control. I have no experience with cisco other than what I have learned in the groups. I think what I need to do is basic, but I am struggling. I need to forward all SMTP traffic to a specific ip address. Can I just create an access list at the very beginning? Is there anything special I need to do with the interfaces? Any help would be very much appreciated.
Here is a little snippet of the code:
