Saw a few warnings/errors today on a specific R80.40 gateway regarding NAT pool exhaustion. This showed up before with R80.30 since we have a source NAT hide rule for traffic from Internet coming to the application.
I went to the gateway and ran a cpview, then looked under Advanced -> NAT. The problematic gateway showed a High Port capacity of 66. The other gateway in the cluster showed 16533, which seems to be the normal value
I've also confirmed this walking SNMP OID 22.214.171.124.4.1.26126.96.36.199188.8.131.52 One cluster member shows a value of 16533, the other shows a number in the mid-60s. Did the same for some other R80.40 gateways and the numbers were always the same.
Very confused why this would be. I do understand the port allocations changed in R80.40 but would certainly expect each member to show the same amount of capacity. I've replicated this in a lab setup and found it's consistent for R80.40, and failing over the firewalls had no effect on the numbers reported.
