Hi Mohammad, 
 The communication of heartbeat cannot be changed to other port than 8347. On the system you may check if the system made a connection using "netstat -s" command. 
 If you redirect the traffic , make sure the traffic is not Natted. If you send the traffic to ISP directly then the traffic would be NAtted and would not be routed to your destination. It must have some tunnel to send your private address without Routing. 
 On the local side you may check the traffic via tcpdump on console. 
 tcpdump 'port 8347
