Hi.

I have recently replaced some SonicWALL devices in our branch offices with Cisco ASA5506X devices. They are running Firepower Threat Defence. 6.2.0.0. (NOT ASA). Behind the ASA5506Xs are Wyse thin client devices, Model No Cx0, Prod Id C10LE. The Wyse devices obtain a DHCP address form the Cisco ASA5506X, then pull down their config from the head office, via a site to site VPN set up by  the Cisco device to a peer.

It mostly works.

The problem I have, is that the Wyse devices do not renew their DHCP lease. Lease time is set to one hour, and there seems no way to change this on the Cisco device. After an hour, the Wyse just displays "DCHP lease expired", and kicks the user out. Power cycling the device allows them to continue their session once more. Other devices (the occasional PC) work fine. The Wyse devices work fine when getting their DHCP leases from other DHCP servers, however every other DHCP server they have used has been configured with a lease of over a week.

It seems to me that the firmware on the Wyse devices have a problem, so I would like to upgrade it. Current versions is 8.0_210. I have checked with Dell, it seems that I need a support contract to access firmware. These devices, however, are documented as "End of life" in May 2014, so a contract cannot be had. This is odd, as several of our devices have a manufacture date of July 2014.

So questions:
1. Has anyone seen these devices exhibit this behaviour before?
2. Any hints as to how I might obtain newer firmware?
