We have several servers that are network load balanced to a common virtual MAC/IP address on our wired network. Those servers have a static ARP entry on our core router/switch (Cat 6509)
Machines on the same VLAN on the wired side can connect to those IP's without any problem. Machines on the wired AND wireless networks that are in different VLAN's are able to connect to these machines.
Machines that are connected to the same VLAN as the NLB's but are on the wireless network are not able to connect to these machines.
They do receive the correct MAC address in their local arp tables, but cannot ping the host IP.
