Hi usually the age-out issue is either a nat issue or a return path issue.
I mean if you have more than one link to the internet, multiple links.
The server must be able to, I am talking from the server, directly from the server, to have correct internet access from the server's private Ip to some test Ip.
Now a nat destination NAT, has to comply with the following.
Referential example: NAT policy:
Origin zone: Untrust/WAN zone Destination Zone Untrust/WAN zone Source Any ( or you filter from X public IPs to establish the connection ) Destination Address: The public IP with which you are doing the NAT / DNAT ( i.e. the External IP of the server, External Public ) Service: You could just set the RDP, example TCP-3389 Source translate: Nothing None Destination Translation: Here at this exact point goes the Private IP, the LAN IP of your server. You can use Translated Port to set 3389.
Now the Security Policy example:
Source zone Untrust/WAN Zone Destination: The destination zone, e.g. DMZ, Trust, Servers, etc. however you have it named. Source Address: Any Destination Addres: The public IP with which you are doing the NAT / DNAT (i.e. the External IP of the server, External Public). In service: You can also use the service to close and only limit to port 3389-TCP-RDP.
Try in each case, NAT and security policy, upload the policy to be one of the first, in both cases.
Now your server must exit on the same link that your request enters so you don't have problems with return traffic.
Validate that the server, that is to say from the private IP of the server, can exit correctly to the Internet, that at the level of routing by the main link and/or the same of the DNAT it works well.
Now also validate that you are placing the correct Ip, that the server, if you arrive from the same LAN or from the same network if you answer the RDP. Validate that from the Server you have Ping with the LAN gateway, you have Ping, with public Ip.
Validate that there is no security profile blocking the connection.
Try the connection from several external connections, from outside the network, not from the inside, but from the outside against that public IP you mention, from your laptop sharing internet with your cell phone via 4G, from a home network, your house, etc.
Greetings
