I have a desktop application which talks to a server using TCP/IP. It was working before but now we are running into an issue. The log message on the server shows that the socket is disconnected after a while, but we are able to exchange heartbeat messages. When I ran the Wireshark tool I get this log which I don't know how to interpret:

4324    36.613058   50.19.123.218   192.168.1.135   
    TCP 843 > bvcontrol [RST, ACK] Seq=1 Ack=1 Win=0 Len=0

6312    61.546839   50.19.123.218   192.168.1.135   
    TCP 843 > nmsd [RST, ACK] Seq=1 Ack=1 Win=0 Len=0

The other thing is when I run this application in the LAN where the server is running it just works fine.

Please help me to understand what is happening in the network.

There's not enough information here to understand what's really happenning, but you might want to have a look for a stateful firewall between 50.19.123.218 and 192.168.1.135. Also check if you've got keepalives enabled on the client.
