I am having some problems with ARP requests from wireless clients to wired hosts. I have a 4402 setup with a a few WLANs and their associated dynamic interfaces. I also have an ASA that is the default gateway for each of the VLANs associated with the 4402's dynamic interfaces. After I associate, I try and ping the default gateway. If I monitor the VLAN, I see the ARP request emitted onto the wired network as usual, broadcast, and I see the reply from the ASA's interface, unicast. The ARP reply never seems to make it back to the wireless client. If I issue the command "debug arp all enable" on the WLC I get the following message:
dtlArpFindClient:ARP lookup for <gateway IP> failed (not a client).
If I issue a "show arp switch" command I see the gateway's MAC address in the table listed as a 'host' type, rather than a 'client' type.
What is strange is I get the same dtlArpFindClient errors when I try and contact other hosts on the same subnet, however I can communicate correctly. The ASA uses the same MAC address across its interfaces, although I'm not sure if this is part of the problem.

This is the start of a display filter cross reference between Wireshark and OmniPeek.
The 1st installment is a table of advanced filters. More filters will be added as time allows.

I have created a Powershell script to automatically add a Wireless Guest User on Cisco WLCs. (tested on 2500 Series)
The script should be completely self explanatory.
