Hello, I have an ASA 5505, firmware 7.2 (4). Configured ACLs, NAT, it's all working, but after a while it seems that running crashes, no longer makes the directions of NATs, the logs until they stop working. To resolve, I have to restart the ASA, and everything will work again. Could it be a firmware problem, someone has had a similar problem?

Hi Eduardo,
Whenever the device stops passing traffic, I would suggest you to kindly take captures on the firewall, to check if the request is going through the ASA and if you are able to get any reply back from the ISP device. Because I had a previous experience where in the ISP device was losing the arp entries aftemr every fixed time and the resolution was to create static arp for the ASA on the ISP device.
For taking captures:

Thanks,
