Do you have a root?

is a dedicated server, we use a network connection Loopback
for example our external ip is 91.121.24.123 and 169.254.25.129 is our internal
portmap through open ports that is the operation
all good but after a few hours the incoming server loses connection, no one else can connect to the server!
