ip route Service-Engine1/0

ADSL Router

Permit IMAP on port 143, security can be enhanced by specifying Amazon web farm address

ip access-list extended inbound-acl
permit tcp any any eq 143
deny ip any any log

Assign the ACL to the external interface

interface Dialer1
  ip access-group inbound-acl in

create a NAT rule mapping 143 to CUE Module

ip nat inside source static tcp 143 interface Dialer1 143
