Hi. I just answered on Your thread (http://forum.proxmox.com/threads/6223-Weird-network-problem-with-Proxmox-1.7-and-1.8), but I'm writing, if You wouldn't get a message about it. The clue is that I don't know what "somebody activated IP/MAC binding in the gateway but forgot to register the pve and the vms inside pve" means. So please, if You could answer on my post with some steps that I must do, on VE to "register the pve and vms inside pve". Thanks a lot in advance! Regards.
