I have 4 ESX servers, one located at our Co-location facility linked to the main site using a LES circuit.
The 3 ESX servers at the main site have no problems, all guests can ping each other on Vlan1
The ESX server at the co-lo is configured with two network adapters teamed together at the switch on Vlan1. The (only) guest can ping some of the machines at the main site if I set one of the adapters to the top of the failover order for the vSwitch and if I set the other adapter at the top of the failover order for the Vswitch it can ping some of the other machines at the main site (including a few of the servers when I set the other adapter the top of the failover order).
Both physical adapters are configured the same at switch and ESX level and I have rebooted the host in case the config had gone up the wall but to no avail!
Has anyone experienced anything similar and know what the problem might be?
