I'm having problems with the DHCP assignments to the guest wireless users in a site.
I'm using a H-REAP setup with 3 WLCs and a number of APs that support H-REAP(1140, 1240).
The remote sites are spread all over Europe.
One of the WLC is used as the guest anchor and the other 2 WLCs are in the same mobility group with it.
I configured a guest WLAN that uses Layer3, web-auth, and also the WLC is used as a DHCP server for the guest wireless client.
The internal users receive IP addresses from the local DHCP server in each site.
Now the problem is that i can't receive IP addresses for the guest users in a newly deployed site.
The strange thing is that they can see the Guest network, they associate to it, but they don't receive Ip addresses for the wireless NIC, and so they can't connect to a website for authentication.
In other sites, the guest users receive IP addresses without any issues.
For what settings should i look in order to solve this problem?
