Unable to see outside network

[MibbleMibble]

I have three machines in a cluster. some are on their separate domain others are not.

dev servers can see each other across two machines, not on the third. they cannot see the world.

also have machines not on dev network but on the same physical host and they can see each other and the world.

best way to troubleshoot this? have any ideas on what to check next?

thank you

Some details about your network configuration will help.

Are the VMs running in the same subnet, or do you have routing in place?

What type of physical switch do you use? Make sure it doesn't have port security enabled, which may limit the allowed number of connections (MAC addresses) on a single physical port.

Please check the VLAN settings (VLANID ) associated with these VMs .

hello,

yes, the three host machines are on same subnet.

I am working on getting more info.

everything worked until Wednesday morning this past week.
