ASA5505 with WRVS4400N on Cox

I've been trying to get my WRVS4400N connected to my ASA5505 on the internet through a Cox connection, but it isn't working.  I cannot get the ASA to be the DHCP server for the wireless router.  I've configured the wireless router as a gateway and pointed the DHCP server to the ASA but no addresses are being passed through to the wireless router.  I've included a copy of my config.

Try running a packet capture on the inside interface and see where the DHCP exchange is failing:

capture capin interface inside match udp any any range bootpc bootps

show capture capin

The following debugs may also help narrow down the problem to the ASA or the router:

debug dhcpd event

debug dhcpd packet
