  • 1.  2 vms in same logical switch cannot communicate

    Posted Nov 25, 2019 11:06 PM

    Hello,

    I have installed NSX 6.4.6.1481, Prepared my three hosts with no issue, set up VXLAN, Added transport Zone and created a logical switch with 2 VMs.

    my to VMs cannot communicate with each other in same VXLAN but they should I think!

    In host Preparation, The firewall is enabled and as soon as I disbaled it, the VMs can see each other.

    Is this normal in this version?

    Do i need to modify firewall rules for this situation?

    Thanks

    Do you have any rules at DFW firewall section ?  What is the default rule under Firewall - General & Ethernet ? , Do a trace-flow and share the results when VM is not able to communicate on same logical switch and host.  Also do check/share the results after following the steps  ->CLI Commands for DFW
