block-allocation (Source NAT Next Gen Services)
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.
Allocate a block of ports for each subscriber to use for source NAT with port translation, except for deterministic NAT. New requests for NAT ports for the subscriber are served from the active block. With port block allocation, we generate one syslog log per set of ports allocated for a subscriber. This reduces the number of logs, making it easier to track subscribers.
