routing between vlan

[Nicolas967]

Hi,

I have a vmware 6.5 cluster (Nutanix) connected to a couple of switchs HPE 10G (JH295A).

3 vlan are configured on these switchs.

VM's in a same vlan ping other eachother VM's at <1ms.

but VM's from one vlan ping VM's from another vlan at more than 30ms...

Each vlan has his own interface.

VM's in vlan 1 (10.248.0.0/24) has a firewall interface for gateway (10.248.0.251).

VM's in vlan 2 (172.28.2.0/24) has the vlan 2 interface for gateway (172.28.2.244)

VM's in vlan 3 (172.20.0.0/24) has a firewall interface for gateway (172.20.0.251)

The switch has only one static route :

destination 0.0.0.0 gateway 10.248.0.251 (firewall) via interface vlan1 (10.248.1.244/23)

I don't understand what's wrong between VM's from differents vlan...

Thanks for your help

Nicolas

Hi,

Thank you for your response but i'm not sure I understand what you want as information. Can you go into more detail about your request?

Thanks

I have advanced in my diagnosis, it is indeed a routing problem, but the switch has nothing to do with it. The problem seems to be related to the firewall.
