RV340. Port fowarding stop working

[Cimmerio]

The configuration is as follows.

• Port 25 (SMTP) is redirected to an internal IP, using the Port Forwarding function.
• Through the Static NAT option, we have redirected several ports with two public IP addresses.

Everything works fine, but in a matter of hours or days, the redirection stops working. Port 25 is no longer accessible, as are the other ports associated with different public IP addresses.

Hi, 
My name is Iliya Gatsev from Cisco Technical Support Team.

I think it would be best if you could call our support line and open a support ticket, so we can do a WebEx remote session and check the configuration.
