I'm probably overlooking something obvious, but I recently started having DHCP issues. Meaning clients have sporadic but frequent problems getting a DHCP address (saying no DHCP server available). I normally use a Windows server as the DHCP server, but when the issue started I enabled DHCP on the ASG and the same problem exists. This seems to affect mostly wireless clients, which would seem to say its somehow related to needing to get DHCP requests through or to the ASG.
For what its worth, I also noticed that some of my Apple devices can no longer see each other (they are all wireless clients). This doesn't seem to be as consistent though.
All of this used to work fine, and I don't recall making any unusual changes. Although my DHCP lease time is long enough that it could have been a while ago that the problem actually first started and I'm only noticing it as leases expire. The Apple issue is fairly recent though.
I'm running my ASG as an HA pair of VMs under ESXi 4.1 (each VM guest on a separate ESX host). Version of the ASG is 8.202. The upgrade to 8.202 is the last change of any significance I've made (well, unless some "insignificant" change turns out to be causing my problem, and then it would be significant :-).
Update...
Seem to have been able to confirm this issue affects wireless clients only. Wireless access works in general, but DHCP and Apple stuff doesn't seem to (Apple home sharing, Apple remote to a PC running iTunes). But wired access works (DHCP, Apple shares work fine, etc.). So, something apparently funny with wireless. I'm using two Astaro AP30s and the wireless network is bridged to the AP LAN. That said, I power cycled one of the APs, my devices connected to the other one, and then things started working. So, maybe it was just gremlins and I "fixed" the problem.
Thanks.
