I'm having networking issues with my new ESXi 5.1 host. I'm pretty sure it's a setting that I missed. I'm getting no ping replies when I'm trying to ping the management or the vMotion vmnic. However, vCenter can communicate with that host just fine, and the other vSwitch handling NFS traffic, I can ping that VMkernel just fine.
Since I can configure only a single gateway address for an ESXi host, I set it to 10.0.128.61/27.
As mentioned I can ping the NFS (VLAN 1002) VMkernel (vSwitch1) just fine whose IP is 10.0.128.40.
However, I cannot ping the vMotion (VLAN 1001) VMkernel with IP: 10.0.128.20/29. I also cannot ping the management (VLAN 1000) VMkernel with IP: 10.0.128.4/29.
However, if I change the default gateway to let's say 10.0.128.6, then all of a sudden I can ping the management VMkernel, but no longer the NFS VMkernel.
On all my other ESXi hosts, I can ping all VMkernels on that host, even though all of them have their default gateways setup as 10.0.128.61.
What do I need to do to be able to ping all of the VMkernels on this new ESXi 5.1 host?
