What causes a SM 450 or 450i in NAT mode with 2000  table entries to lock up and become unresponsive?? I adjusted timeout minutes but no change. I also increase the table size from 2048 to 5000 but still no change.

Hi,

Please share CNUT capture of SM.

NAT table is full, that explain why you see issues. Does setting 8192 NAT table size still didn’t helped?

I am unable to login to SM remotely once  the SM reaches 1500 entires.  I can ping the device but unable to login.
