Hi,
Got a setup with a RAP-155P (v 6.4.2.6) which has a VPN to a cluster of 7010 controllers (v 6.4.2.10). Everything works fine, but I have an issue with the DHCP distributed L3:
When a client connects to the SSID linked to the VLAN (2) with the distributed L3 dhcp, I see the dhcp discover packet coming out of the aruba controller in the datacenter firewall logs (there is a firewall at the datacenter where the aruba controllers and dhcp server are located), and i see a response coming from the dhcp server towards the aruba controllers.
I've set up logging on the IAP as well, and the log shows that the initial dhcp packet is indeed being sent, but there is no returning traffic.
I can reach the DHCP server pinging from the IAP and vice versa, so the path is OK.
When I put a static IP on the wifi client, everything is working, I can reach the servers in the datacenter.
Any ideas on how to troubleshoot this?
My suspicion is that the returning traffic is being dropped by the aruba controller at the datacenter, as i don't see anything in the IAP logs. The datacenter is remote, so going on-site for a packet capture is an absolute last resort.
Any help is appreciated!
Regards,
Dante
