I think I'm having issues with our ESXi 4.1 hosts not passing GARP traffic. I am trying to move a secondary IP between two virtual linux servers. Immediately after bringing the IP up on the second server I issue an arping to advertise the new location. It doesn't look like this reaches the virtual servers on another host. I've also noticed that if I try to scan our network via nmap from one of these virtual servers I only get the Up responses. When I do it from a physical linux server I also got Down responses. I'm wondering if this is related to the same issue. I've found several other posts that talk about this issue but I haven't found a solution yet.
