Is it new Setup or working earlier and now facing issue?

 

Sometimes issue arise due to TCP profile timeout setting. Did you get chance to increase timeout value to 1800Sec(Default 300Sec)?

    Hi Rock, We haven't changed the default timeout value, do you encounter this type of issue before? This is working in different technology, after we migrate it to F5 that is the time we encounter this.

    Yes. Can you please capture tcpdump on F5 & unix system also and check if any TCP session is taking longer time to transfer packet.

    @Rock we don't have captures from client side, but client insisting that once they send data the ssh tunnel breaks. We just have packet captures in F5 side and we cannot see any data passing.
