IAP with Juniper SRX240 firewall

I am trying to set up a very small wireless network, using three IAP-105 access points and a Juniper SRX240 firewall.  I have set up three VLANs on the SRX (VLAN 1,2, and 3) and trunked them on the ports that the APs are plugged into.  The native VLAN on the firewall is VLAN 1 and the firewall is providing DHCP services to both the APs and the client PCs.  I am able to get the first AP to come up and advertise the WLANs that I have configured.  I am able to browse to the management interface on the master AP via the advertised WLAN.  The APs appear to be getting an IP address in the correct VLAN from the firewall as evidenced by the ARP table on the firewall.  And I am able to attach to each of the SSIDs and get an IP address in the correct subnet/VLAN.  But when I plug in the second AP it doesn't appear to connect to the master and the 802.11a/n and 802.11b/g/n lights on the second AP are amber (radio enabled in WLAN mode).

 

Has anybody ever done this sort of configuration, or have any clue as to why the APs can't seem to interact properly?

 

Regards.

All three APs need to get an ip address in the same subnet.  You can plug into the console port of the second access point to verify if gets an ip address in the correct range AND if it sees the first access point.

Thank you.  It appears from the SRX arp table that both APs are getting an address in the same subnet.  Do you know what mechanism the IAPs use to communuicate with each other?

I am going to try turning off the ALG functions withing the SRX firewall.  In case this doesn't work, any other suggestions would be greatly appreciated.

I discovered the problem: two of the three IAPs that were sent to me were not for use in the US.
