R510/R600 WAN DHCP IP issue

[Anonymous]

I have an R510 with Unleashed 200.6 and R600 with Unleashed 200.7 connected to a Juniper SRX 240 firewall. The SRX has a DHCP server with reservation assigned for the APs' WAN but for some reason the IP address is being acquired and released multiple times. If I don't have reservation assigned the IP addresses will go from my subnet's low range and increasing around every 15-30 seconds.

I know I can always assign a static IP to the WAN address, but would like to correct this problem. I downloaded the logs and here's a snippet:

x.y.z.252 is the reserved IP. The problem is if I were to disable reservation I'd never login and obtain the logs before the WAN IP changes again.

I'd like to add that with reservation things work. All my VLANs (the WAN port is connected to a trunk and it's responding to the correct pool assigned to the port's PVID) and SSIDs all function. I've only tested with 1 client but it has internet access. I can also ping the APs by their reserved IPs even though after several minutes the address binding entry will disappear from the SRX. The DHCP server is fine--it works as expected with a Juniper AP and Windows notebook.

I have been troubleshooting on the R600 but since I have a brand new R510, I decided to see if it was an issue with the R600. The R510 was just configured using the setup wizard.


Thanks!
