I would like to set up external access to my UC560 for IMAP for iPhones and Outlook clients. Everything works great on the LAN, not I want to extend it to off-net devices. I have a DNS entry pointing to my static IP. The UC560 is also my edge device to the WAN interface is plugged into the cable modem. What is the config I need on the UC560 as far as NAT and access rules go? My current interface configs are below:
interface GigabitEthernet0/0

ip address 24.24.24.24 255.255.255.224
ip access-group 104 in
ip nat outside
ip inspect SDM_LOW out
ip virtual-reassembly in
load-interval 30
duplex auto
speed auto
