If you do not choose a server type, all traffic intended for the publi c IP address
you choose for the server will be routed to that address, and no port translation
will be done.

Original Port

Enter the port number used by the server to accept service requests from the
internal network.

Translated Port

Enter the port number used by the server to accept service requests from the
Internet.

Protocol

Choose TCP or UDP for the protocol used by the server with the original and
translated ports.
Advanced NAT Wizard: ACL Conflict
If this window appears, Cisco SDM has detected a conflict between the NAT
configuration and an existing ACL on the WAN interface. This ACL may be part
of a firewall configuration, a VPN configuration, or the configuration of another
feature.
Choose to modify the NAT configuration to remove the conflict, or choose to not
modify the NAT configuration. If you choose to not modify the NAT
configuration, the conflict may cause other features you have configured to stop
working.
