passing traffic but fails to connect

by oguz   Last Updated July 10, 2018 18:00 PM

we have a weird issue about when we trying to sftp(port:22) to different company server, connections have been lost time to time, but checkpoint fw pass through all the traffic. When we tried to capture we saw that connection only lost when source port is like 10400 10500 and 10600 ports.(but it is a random action) also, in this situation, protocol fails like that SYN packet sending and reverse packet get only ACK. Any idea of, how we can solve this?
