Usg Flex 100: sometimes Nat rules stop working
Hi
I have an usg Flex 100 with latest firmware
After some year of perfect working from 1 month, sometimes, Nat rules stop working and the workstation software cant receive traffic from external call (external devices call the local software for record some status information)
Solution: uncheck Nat rules
Wait some minutes
Recheck Nat rules
I cant find other solution....
Thanks

We suggest you can update to our latest firmware V5.36P2 for further verification. If it still has a problem, please share your running-config file with us via private message and indicate is which NAT rule cannot work sometimes. Thanks.

Why would a alarm systems need inbound traffic? Thats bad it should be outgoing to a server
how do you know its stopped working?

the USG FLEX is on a alarms installer.
the systems of the various customers connect to communicate
- the state in life
- eventual alarms moreover,
the control units report the lack of communication with my client's alarm centre
also via direct connection (link to the web server of the alarm center pc hosted behind the USG http://333.555.222.111/subfolder ) technicians can access the system to verify customer problems etc.
when the rules are blocked, the customers' systems are unable to send reports and are blocked, furthermore the system becomes unreachable at the address used by the technicians
a simply deactivation and reactivation of the rules unlocks the issue

Not sure it will help but try increasing UDP Session Time Out to 120 in Session control
you could do a packet capture of the port will help
