weird networking problem

I've got a weird one. Starting recently, we cannot access our vmware hosts console connection from any other subnets. Additionally, all 3 of my linux hosts, cannot traverse subnets, but all 40+ of my windows VMs can. So all my VMware stuff is in Subnet A. If I go to another server in Subnet B, I cannot ping or putty, or use the Vmware console on the Vmare hosts. From Subnet A it works fine. From Subnet B I CAN access the VC, which is on a windows box in Subnet A. Of course if I try to remote console a VM, it fails because those are the hosts that cannot be accessed. I've triple checked Subnet mask and gateway on all machines and DNS is out of way because I am testing with IPs. We are not doing VLAN taggin on my virtual switched. I can't think of anything we've changed and honeslty this started happing over the Thanksgiving holiday when the office was closed for 4 days.

Any ideas? Let me know if you need more info.

Sounds like your network or firewall shop decided to use that long holiday weekend to make some changes... Smiley Wink

Of course the network team says they didn't and the networking all looks normal. My only concern with troubleshooting is that all cross-subnet traffic works, except to/from the 3 vmware hosts and the 3 linux VMs on those hosts. Any windows VMs or any non-vm's work fine. Puzzling.....
