I have a 1800 router and my ISP blocks port 25 (smtp). I need to configure inspect and port-map esmtp to port 587, but I can't configure this. If i configure port-map on port 587 directly (not port-map esmtp), the applications not works correctly (very slow access).

The question is: My IOS support port-map esmtp service (not smtp) ? If not, what I need to solve this ?

My data are:

Cisco IOS Software, C181X Software (C181X-ADVIPSERVICESK9-M), Version 12.4(6)T9, RELEASE SOFTWARE (fc2)

Thank you very much.

IOS has to support the ip port-map for this to work. Here is the format "ip port-map appl-name port [tcp | udp] [port_num | from begin_port_num to end_port_num] [list acl-num] [description description_string] " used. Also make sure you ISP doesnt block this port. Refer the URL
