Question

FortAP220B DHCP no ACK

Hi, I' ve recently tried adding a 220B to cover a part of the building that the wifi signal from the fortigate 60C is not covering. Its my understanding that I need to add DHCP option 138 to the DHCP server first, which I' ve done as follows on a linux dnsmasq dhcp server: #wifi controller dhcp-option=138,10.0.0.254 10.0.0.254 being the fortigate 60c for example. However when checking the DHCP logs I get: Apr 3 11:45:38 localhost dnsmasq[5313]: DHCPDISCOVER(eth0) 00:09:0f:XX:XX:XX Apr 3 11:45:38 localhost dnsmasq[5313]: DHCPOFFER(eth0) 10.0.0.86 00:09:0f:XX:XX:XX There is no DHCPACK coming back from the 220B to take 10.0.0.86 as its IP. Could it be that the format I have used for the 138 option is wrong? Also is it possible to use fortiexplorer via USB to manage the 220B? Its worth noting that I have bridged the wifi and the lan on the fortigate 60C currently. The wifi works fine on the 60C, I am using v4 MR2 with the latest firmware for MR2 currently on the fortigate.

    Hi, Is the FAP on the same subnet as the Fortigate ? If yes, then you dont need to use it. It´s only used when the Fortigate is on another subnet and not on the same L2 network.

    Hmm yep, its on the same subnet (if it got an IP off DHCP) however the 220B is not taking an IP and I cannot see it on the fortigate webadmin panel.

    I don' t know what firmware version it has as I can' t get it to take an IP off the DHCP server as yet. I presume I' ll have to connect to the default IP directly? The USB according to the instructions can' t be used just yet.

    no the USB is not working, you can connect to it by IP or use the console, i think you need to upgrade the firmware before doing anything else

    Theres a bug id 154429 on v4.0 MR2 Patch 10 which that patch supposedly fixes that does seem to point to a DHCP issue. I' ve managed to telnet it OK and it can take a fixed IP no problem, however I cannot see it on the fortigate 60c admin panel at all. Is there a command in telnet for the AP to show the firmware version its running?

    Version: FortiAP-220B v4.0,build214,110331 (MR3) Serial-Number: FAP22B3U11014328 BIOS version: 04000010 Regcode: E Hostname: FAP22B3U11014328 Branch point: 214 Release Version Information:MR3 The above is what I have on the FortiAP. And below is what I have on the Fortigate 60C Wifi: v4.0,build5904,120224 (MR2) The above seems to state MR3...if that is the case then I presume I should not have had any DHCP issue? I also assume that this means I have to either upgrade the 60C fortigate to MR3 (I' m not too keen on this) or downgrade the AP to an MR2 version. MR2 Patch 11 for example?

    actually i would upgrade the FAP to build 224, and i assume you are using the special Wireless Controller MR2 Patch 10 ?

    I' ve only recently started using fortigate equipment so I' m not sure! lol. FWF_60C-v400-build0342-FORTINET.out is the file I have flashed the fortigate 60C with which results in v4.0 build5904 120224 (MR2). Oddly enough the MR2 Patch11 folder I got this from has disappeared from the FTP server today, just to confuse me even more :) As far as I know that is the latest version, however I do not know if thats the wifi controller version or not (I' m guessing it isn' t). Do you know which file/folder I should be looking in for the wifi controller version you mention? Sorry to put you through this and thanks very much for the help btw ;)
