Hello Mike, We have investigate further and there in we found that there's an continues ACK/SYN/PING traffic flows between server and client for an absolutely idle session.
Due to which number of packets and in turn data exchange increases continuously for an absolutely idle session. Can you please guide us on how to stop continues server PING/NOP/ACK/SYN ? can we configure some parameters in guacamole-client to achieve this ?
