| udp | Specifies User Datagram Protocol (UDP). |
| protocol_num | Specifies the IP protocol number. The range is 1 to 255. |
| port | Specifies modifying an L4 port. |
| port_num | Specifies the L4 port number that needs to be translated. |
| new-port | Specifies the L4 port after translation. |
| new_port_num | Specifies the L4 port number after translation. |
| none | Deletes the protocol configuration. |
N/A.
The following example specifies for rule "rule1" that the destination protocol is TCP and the port is translated from port 1 to port 2:
# configure ip nat rule rule1 destination protocol tcp port 1 new-port 2
This command was first available in ExtremeXOS 31.2.
This command is available on the switches that support the IP NAT feature. For information about which switches support this and other features, see the ExtremeXOS and Switch Engine 31.7 Feature License Requirements document.
