    I have also run into this caveat. I am running 13.1.1.4 on VMware Workstation 15 on Fedora 29 Linux kernel 5.0.4

    tmsh modify /sys db tm.tcplargereceiveoffload value disable

     

    tmsh modify /sys db tm.tcpsegmentationoffload value disable

     

     

    It appears that WMware loses packets when offload is enabled.

Can you check your logs? Post any errors you see here to diag this issue? Did you configure a sync vlan....can you telnet to each other device on ports 443,22? Are both devices part of device trust? run the below commands

 

grep -i cmi /var/log/ltm

 

grep -i configsync /var/log/ltm
