Release Information

Statement introduced in Junos OS Release 19.3R2 on MX Series routers (MX240, MX480 and MX960) running Next Gen Services with the MX-SPC3 services card.

Description

Configure automatic port assignment for source NAT with port translation, except for deterministic NAT. Automatic port assignment uses the port range 1024 through 65535. Specify either random allocation or round-robin allocation. Random allocation randomly assigns a port from the range 1024 through 65535 for each port translation. Round robin allocation first assigns port 1024, and uses the next higher port for each successive port assignment. Round robin allocation is the default.

Options

random-allocationRandomly assigns a port from the range 1024 through 65535 for each port translation.
round-robinFirst assigns port 1024, and uses the next higher port for each successive port assignment. Round robin allocation is the default.
