vpim external

To configure NAT entries for peer messaging gateways or endpoints, use the vpim external command in Cisco Unified Messaging Gateway (Cisco UMG) NAT configuration mode. To clear the configuration, use the no form of this command.

vpim external ip_addr port-number

no vpim external ip_addr port-number

Syntax Description

ip_addr	External IP address for VPIM port.
port-number	Listening port number for VPIM requests.

Command Default

The default port number for VPIM requests is 25.

Command Modes

Cisco UMG NAT configuration (config-nat)

Command History

Cisco UMG Version	Modification
1.0	This command was introduced.

Usage Guidelines

If multiple messaging gateways are behind the same NAT device, endpoints should have the capability to talk to messaging gateways on other ports in addition to 80 (HTTP) and 25 (VPIM), because they may be sharing the same external IP address.

Examples

The following example sets the external IP address and listening port for VPIM requests:

umg# config t

umg(config)# nat endpoint id 1000

umg(config-nat)# vpim external 192.0.2.24 26

umg(config-nat)# end

umg(config)#
